Next pre is up, changes since pre2:

Yesterday with pre2 I had dire problems, so many that I gave up on making a proper bug report but basically it freaked out completely with scsi host resetting errors and kernel panic messages that took control over my tty + kbd when I tried to do the formatting part - and I was not able to log anything either. Eventually I had to push the big button. I tried again today with pre3 and still I don't get past the formatting hurdle. Here's what happens when I try to format a disc: -------------------- root@olafrye:/home/mojo# cdrwtool -d /dev/sr1 -q using device /dev/sr1 768KB internal buffer setting write speed to 12x Settings for /dev/sr1: Fixed packets, size 32 Mode-2 disc I'm going to do a quick setup of /dev/sr1. The disc is going to be blanked and formatted with one big track. All data on the device will be lost!! Press CTR L-C to cancel now. Initiating quick disc blank Disc capacity is 274944 blocks (549888KB/537MB) Formatting track Writing UDF structures to disc 7200 (CEST)/-120 -------------------- While writing those structures my system freezes completely and once again I have to resort to power recycling. Surely my system consists of some cheapo hardware, the cdrw device being a Phillips CDD 3610, but I think it ought to work anyway. There are two things I noticed from the output above: 1) that cdrwtool sets the writing speed to 12x by default while my drive is only capable of 2x. I suspect that it should not really matter and that using 12x would just mean that the maximum speed of my drive is being used but nevertheless I might ask: do you think that it might make a difference setting the speed with the "t" parameter..? 2) The disc capacity is being calculated as 537 mb - why..? As for the rest I have followed the install instructions in the readme file meticulously. I have compiled with modules and I have enabled write caching and retained the default of 256 kb of data gathering buffer. I got the UDF cvs tree and compiled and installed the udf module. Prior to this I bumped up my kernel version to 2.4.4-pre6 and rebooted. Regards, Morten -- "It is characteristic of the present time always to be conscious of the medium.
