hi there is something strange: - i did a cp -r /etc /mnt/cdrom (~ 7 Megabytes) - everything seems to work, program completes - i am able to browse the disc - BUT, when i did a sync, i got the following crap on /var/adm/messages, and the command did never complete. - apart from this, the machine seems to work normally ....

Yamaha writers
by Roberto Pirrone 29 Mar '00

29 Mar '00

Hi all, 1) drivers/ide/ide-cd.c, line 2872 ide_cdrom_init was declared as static. this does not work for compiled kernels 2) packet 0.0.1l, 2.3.99-pre3-8, i was able to make, mount and use a CD-RW, using a Yamaha CRW4416S (scsi). Wow! 3) same as above, with a Yamaha CRW8424E (ide), cdrwtool hangs forever, /var/log/messages says "hdc: lost interrupt". this happens around the "Writing UDF structures to disk" phase Hope it helps roberto

cannot format RW media!
by Mark Robinson 29 Mar '00

29 Mar '00

Hey all, Greetings! I have a JVC-2042 (uses the TEAC cdr-50 driver under cdrecord), that I cannot get to work with my current setup. I'm using 2.3.99-pre3, udf-0.9.1. I use an adaptec 2940 UW, with 2 other devices on the bus, a nec 24x cdrom and a WD Enterprise 4.2 gig HD. Oh yeah, the machine is a Dell PowerEdge 2200 PII 266 (dual processor, I only have one processor on the MB). The kernel is compiled for SMP. I did compile the kernel correctly with packet writing enabled. When I issue the ./cdrwtool command specified in the UDF documentation, I get the following error on standard output: penguin:/usr/src/udf-0.9.0/tools# ./cdrwtool -d /dev/scd1 -s -z 32 -p 1 -w mode2 -q using device /dev/scd1 ok, want to set packet size: 32 fixed packets mode2 sr1: CDROM (ioctl) error, command: 0x43 00 00 00 00 00 00 00 0c 00 [valid=0] Info fld=0x0, Current sr00:00: sns = 70 8 ASC=8f ASCQ= 0 Raw sense data:0x70 0x00 0x08 0x00 0x00 0x00 0x00 0x0a 0x00 0x00 0x00 0x00 0x8f 0x00 0x00 0x00 0x00 0x00 and this logged to /var/log/messages: Mar 27 16:53:08 penguin kernel: [valid=0] Info fld=0x0, Current sr00:00: sns = 70 8 Mar 27 16:53:08 penguin kernel: ASC=8f ASCQ= 0 Mar 27 16:53:08 penguin kernel: Raw sense data:0x70 0x00 0x08 0x00 0x00 0x00 0x00 0x0a 0x00 0x00 0x00 0x00 0x8f 0x00 0x00 0x00 0x00 0x00 Mar 27 16:53:08 penguin kernel: cdrom: This disc doesn't have any tracks I recognise! On the first log sample, everything from "sr1" to the last line is repeated 3 times the first time the command is attempted, then only once apon subsequent execution of the ./cdrwtool command. In the cdrecord documentation, Joerg Schilling states that CD-RWriters that use the TEAC cdr-50 interface have to be informed of the size of the image before actually writing it. I thought that may be relevant. The writer works with gcombust. If I can send any other information, please let me know, I will do what I can Thanks, Mark Robinson

Still no success with packet-0.0.1l
by Arnd Bergmann 25 Mar '00

25 Mar '00

Packet-writing is getting better for me, but still won't let me mount a disk. The first bug I found is easy to work around, but probably hard to fix. My AHA1542 needs ISA-DMA clean buffers from sr_packet (sr.c:656). I was the one who submitted the patch for bounce buffers there, but unfortunately it is buggy, sorry about that. The driver won't work when the function is called with a buflen > PAGE_SIZE, because scsi_malloc() does not allocate more than one page at a time. This bug is triggered for example by 'cdrwtool -u', which tries to write 64k packets through sr_packet(). A quick workaround for me was to give mem=16M as a kernel parameter, but that is obviously not a solution for the problem. The same problem is in sr_do_ioctl, although that is currently not called with buflen > PAGE_SIZE, AFAIK. Both sr_packet and sr_do_ioctl should also check for buflen==0 before calling scsi_malloc(). My further thoughts on that problem: - Can this be only be solved by 'persistent DMA buffers' like the sound driver does or is there a better way to do it? - Will it be possible to write packets of a size > 64k with ISA DMA? I remember something about limitations of the DMA controller. Another, probably unrelated, bug showed up when trying to mount pktcdvd0, where the aha1542 driver panics with "Foooooooood fight!". I can reproduce this as well by writing small blocks to the pktcdvd0 device. As long as the block size is a multiple of 4096, it works correctly. After reading a smaller block, the first write call fails. For example, > dd if=udfimage of=/dev/pktcdvd0 bs=65536 count=1 > dd if=/dev/pktcdvd0 of=tempfile bs=2048 count=1 > dd if=udfimage of=/dev/pktcdvd0 bs=65536 count=1 will panic at the third command. I've attached a transcript of my syslog messages to this mail.

patch: packet-0.0.1l
by Jens Axboe 23 Mar '00

23 Mar '00

Hi, New release of the packet writing module for ATAPI and SCSI CD-RW units. Get it here: ftp://ftp.*.kernel.org/pub/linux/people/axboe/packet/packet-0.0.1l-2.3.99-p… The diff is currently against 2.3.99-pre3-8. Important changes in this release: - Fix nasty bug where multiple writes would not get stored in the correct order when requeued - Fix SCSI segment miscount. SCSI has too many rules that pktcdvd should not know about, so let it recount - Elevator nr_segment better, but not perfect. Minor problem - Fixed sr as builtin bug, thanks to Arnd Bergmann <arnd(a)itreff.de> - New PACKET_READONLY flag to catch writes on ro media, originally because of UDF problem - Made pkt_recheck_segments standard - Made pkt_queue_request "nicer" wrt elevator - Try to detect cases where we are loosing performance on duplicated writes. Hasn't caught anything yet... - Update udf-0.9.1 to be aware of CDROM_SEND_PACKET changes - Ported to pre-2.3.99-pre3-8 -- * Jens Axboe <axboe(a)suse.de> * Linux CD-ROM Maintainer * http://www.kernel.dk

[patch] compile error in non-module sr.c (2.3.52-3/0.0.1k)
by Arnd Bergmann 23 Mar '00

23 Mar '00

Hi! I wasn't able to compile the current version of the scsi cd-rom module, when trying to put it in the kernel (don't ask why I would want that). My patch should use the macros correctly now, but it still has the ugly '#ifdef MODULE', because the scsi drivers (sr, sg, etc.) already get initialized by scsi.c, so sr_module_init must /not/ be called separately when booting. Unfortunately I still was not able to get packet writing itself working on my system, but I'll have to keep playing a bit with it before giving a full bug report. Might also be a hidden aha1542 bug.

slowly writing
by Gerald Haese 20 Mar '00

20 Mar '00

Hi! I have a SCSI-CDRW (YAMAHA CRW4416) and I currently use the packet-0.0.1k patch for 2.3.52-3. It also works in 2.3.99-pre... I've the same problems like Ben and got a kernel panic, too. My box was not able write it to the log file so I can't mail the outprint :-( An other question: Why is writing to disk so slowly? The CD-RW is recognized correctly as 6/4 (R/W). It writes withe a two-seconds-clock to the disk, so write and sync of huge files takes terribly match time :-( Gerald -- Sent through GMX FreeMail - http://www.gmx.net

Prob: mkudf and cdrwtool (version 0.9.1) for pre-2.3.52-3
by christian 20 Mar '00

20 Mar '00

Hi, I'm doing my first steps with udf so .... as there are no stupid questions .... ;-) I have a little problem to compile mkudf and cdrwtool. (version 0.9.1) First, I applied the packet-0.0.1k-diff patch against pre-2.3.52-3 kernel. -> ok (Originally 2.3.49 with patches 2.3.50 -2.3.51 - pre2.3.52-3.) Do I need to apply all pre2.3.52-x patches or is it enough to apply the last one (nr. 3 in my case) ? Then I have compiled the new kernel with blockdevice UDF(module) and filesystem UDF(module) and UDF-WRITE. -> reboot: ok Afterwoods I tried to compile the udftools and I had the following errors (see bellow). Trying to compile cdrwtool gives exactly the same error output. Compiling the mkudf and cdrwtool against 2.3.49 was okay, but compiling against 2.3.49 and using for pre-2.3.52-3 seems not to be the best solution. I have used cdrwtool and chkudf , but chkudf wasn't very happy with the result, but I don't trust these results with this version mixture. Or am I wrong with this presumption? Or is there existing an udftools for 2.3.52-3 ?

PATCH: packet-0.0.1k
by Jens Axboe 15 Mar '00

15 Mar '00

Hi, I've made a new release of the CD-RW packet writing module. This one is against pre-2.3.52-3, so expect a new one as soon as 2.3.52 is out. There's no pktsetup of UDF diff included in this version for that reason, use a pktsetup from the j version. ftp://ftp.*.kernel.org/pub/linux/kernel/people/axboe/packet Changes: - Modified to work with changes in recent 2.3 block layer - Fixed devfs permissions - Added reference count member to pd - Misc CD-ROM fixes for SCSI, ATAPI, and old drivers - Fix oops when minor != 0 was used. Thanks to Peter Osterlund <peter.osterlund(a)mailbox.swipnet.se> for the fix - Fix missing break in sr.c. Thanks to Gregory Zornetzer <gaz(a)nmrfam.wisc.edu> - MCN setting for mode2 discs failed for some reason - removed - Added data direction, to reflect recent SCSI changes - Speed setting changed - Added CAP_SYS_ADMIN checks for setting up / removing devices - Make elevator aware of WRITE_PACKET command - Misc other minor fixes - Ported to pre-2.3.52-3 We also have a dedicated mailing list for this module now, packet-writing(a)suse.com.

Next release
by Jens Axboe 13 Mar '00

13 Mar '00

Hi folks, I'm getting ready to do the new release -- problem is, my test machine is currently without a network adapter which means I can't do testing. So the release will be tomorrow. On a related topic -- I'd like to have a web page for the project. Nothing grand, just an informational site explaining how to use packet writing etc. I don't have time to do it though (and with my web page abilities, anything I do looks like crap anyway ;), so if someone would like to take this job I can give you an account on kernel.dk. I'll help with info, naturally. -- * Jens Axboe <axboe(a)suse.de> * Linux CD-ROM Maintainer * http://www.kernel.dk
