2.6.8: IDE cdrecord problems

Umm, interesting. I've had the same problem and I blamed the drive, but I've the same logs:

This log repeats for every cd i tried to burn.

Unfortunately I've no blank media until Monday I can go to the shop :) so will test a stock kernel soon.

Running:

ellugar:/var/log# uname -a
Linux ellugar 2.6.8-rc4 #48 Fri Aug 13 19:25:22 CEST 2004 i686 GNU/Linux

Debian unstable.

More info and testing on request.
Any changeset to revert?

Please cc me as I'm not subscribed to lkml.

Hi,

In my case it is a stock kernel. Also, I never saw any of these messages before...

I can confirm that this also happens here, on 2.6.8rc4 and possibly earlier rcs (should probably have reported it earlier). :)

I can burn DVDs with growisofs without problem, but burning an audio CD with cdrecord OOMs everything and the box chokes. slabinfo did not appear to report anything large if I remember correctly, but I'm not certain.

Simon-

Hi, sorry I wasn't clear, I'm using too stock 2.6.8.1. I meant will test with stock 2.6.7.

Also I think it may be related to some of these changelogs:

very likely:
[PATCH] BIO page refcounting fix:

http://linux.bkbits.net:8080/linux-2.5/[email protected]

I'll try to patch -r this and test on Monday.

these changesets are also cdrom or bio related, althought I don't think are causing any trouble:

bio_copy_user() cleanups and fixes:
http://linux.bkbits.net:8080/linux-2.5/[email protected]
[PATCH] fix cdrom cdda rip single frame dma fall back
