Linux-2.6.0

I was about to update my kernel to the new stable 2.6.0, but notice Jens has added some changes since test11. Is there any reason to suppost the test11 patch wouldn't work? I guess this is just a way of saying 'Can we have a 2.6.0 patch please Peter?' -- Richard A Downing FBCS http://www.freewebs.com/109bean/ Anyone sending unwanted advertising e-mail to this address will be charged $25 for network traffic and computing time.

packet-2.6.8 problems
by Graham Vincent 17 Aug '04

17 Aug '04

Hello. I have a 2Ghz Celeron/Asrock motherboard/HP Dvd writer dvd300n that has been working well packet writing CDs with a 2.6.7-rc2 kernel using Fedora Core 2. When I saw DVD+RW was supported with the latest patch I thought I'd upgrade... I downloaded the full 2.6.8 kernel source and patched it up to 2.6.8.1 with no errors. Applied the packet-2.6.8 patch, again no errors. Built a new kernel, installed the nvidia drivers, all OK. Patched the udftools-1.0.0b3 and rebuilt, all OK. Inserted a known good CDRW and reformatted: # cdrwtool -d /dev/hdc -q Took a while but completed cleanly. Then tried: # pktsetup /dev/pktcdvd0 /dev/hdc open packet device: No such device or address Nothing found in /var/log/messages to give any ideas. I have the block 97 devices pktcdvd0 and pktcdvd1 in /dev but some of the recent traffic on this list has referred to a /dev/pktcdvd directory that is non-existant on my machine. I've hunted through the documentation but can't find any reference to this directory. What am I missing here? Any suggestions welcomed. Thanks, Graham

packet-2.6.8
by Peter Osterlund 17 Aug '04

Here is a patch for 2.6.8: http://w1.894.telia.com/~u89404340/patches/packet/2.6/packet-2.6.8.patch.bz2 Note that an updated pktsetup program is required. Get the udftools patch here: http://w1.894.telia.com/~u89404340/patches/packet/udftools-1.0.0b3.patch.bz2 Changes since previous version: - Get the block device size right after switching between CD and DVD discs. - Replaced the pd->bio_queue linked list with an rbtree. - Removed the "enabling write caching" warning, because it kills sparc64 builds. - Added a compat_ioctl for 64bit machines. - Get rid of the ioctl interface and use an auxiliary character device instead to control device bindings. This requires corresponding changes in the pktsetup program. - pkt_iosched_process_queue() failed to enable maximum read speed on the Iomega Super DVD 8x USB drive. - Simplified the code in the pktcdvd driver that ensures that write requests are not larger than the packet size. - Document that pktcdvd block devices have a 2KB block size. -- Peter Osterlund - petero2(a)telia.com http://w1.894.telia.com/~u89404340

Hi, Will the 2.4.7 dvd+rw patches work with this? Or should I just try it? They seem to apply without too much trouble. I was very pleased to be able to use my drive with 2.6. I'm hoping that the 2.6.8 will fix a problem with a usb storage device I have... -- Thanks, M

Packet-writing with kernel 2.6.3
by falolaf 01 Aug '04

01 Aug '04

Hello, I have for some time now tried to get packet-writing to work with kernel 2.6.3. I can get it to work if I add scsi-emulation for my cd-rw, but I recieve a message that it's deprecated to do so and I should use ide-cd. So I try to do this without emulation. No problem with: cdrwtool -d /dev/cdrom -q No problem with: pktsetup /dev/pktcdvd0 /dev/cdrom No problem with: mount /dev/pktcdvd0 /mnt/cdrw -t udf -o rw,noatime When I copy a file to the disk the led is flashing as usual, but when I try to copy another file nothing happens. It doesn't matter how long I wait, I can't unmount or eject the device. Does anyone have any sugestions?

Hello, that was a long time I haven't problem with this patch, one = year I think, sign of a good job :-) . This is my config: -debian kernel sources 2.6.7 patch 2.6.7 (patch the debain kernel sources without any pro= blem) -dell gx270 with a CDRW/DVD samsung SN-324F with the U204 fi= rmware (it's not a dvd burner) After installing my new patched debian 2.6.7 kernel, I would= like to format a cdrw.=20 The installation is all right (all modules and devices installed,pktsetup is mapped on /dev/hdc). i tried to format a verbatim 8-10X writing compatible: $cdrwtool -t 10 -d /dev/hdc -q setting speed to 10 using device /dev/hdc 1914KB internal buffer setting write speed to 10x Settings for /dev/hdc: Fixed packets, size 32 Mode-2 disc I'm going to do a quick setup of /dev/hdc. The disc is going= to be blanked and formatted with one big track. All data on the de= vice will be lost!! Press CTRL-C to cancel now. ENTER to continue. Initiating quick disc blank Disc capacity is 295264 blocks (590528KB/576MB) Formatting track start=3D0, blocks=3D16, type=3DRESERVED start=3D16, blocks=3D3, type=3DVRS start=3D19, blocks=3D237, type=3DUSPACE start=3D256, blocks=3D1, type=3DANCHOR start=3D257, blocks=3D31, type=3DUSPACE start=3D288, blocks=3D32, type=3DPVDS start=3D320, blocks=3D32, type=3DLVID start=3D352, blocks=3D32, type=3DSTABLE start=3D384, blocks=3D1024, type=3DSSPACE start=3D1408, blocks=3D293568, type=3DPSPACE start=3D294976, blocks=3D31, type=3DUSPACE start=3D295007, blocks=3D1, type=3DANCHOR start=3D295008, blocks=3D160, type=3DUSPACE start=3D295168, blocks=3D32, type=3DSTABLE start=3D295200, blocks=3D32, type=3DRVDS start=3D295232, blocks=3D31, type=3DUSPACE start=3D295263, blocks=3D1, type=3DANCHOR Writing UDF structures to disc wait_cmd: Input/output error Command failed: 2a 00 00 00 00 00 00 00 20 00 00 00 - sense = 02.04.04 wait_cmd: Input/output error Command failed: 2a 00 00 00 00 00 00 00 20 00 00 00 - sense = 02.04.04 Quick setup complete! -------------------------------------------- After this, the disc always turn in the drive and I can not = get it out without force it.
