------- Comment #3 from [EMAIL PROTECTED]  2007-11-20 01:26 -------
I tried passing acpi=off in grub, it didn't make a difference. Interrupts also
looked to be the same.

I mistakenly said I could access the drive at all this is untrue. I am able to
mount and transfer files, I can burn a disc with growisofs however wodim and
k3b do not work.

This is the problem, with wodim if I enter a command like

wodim -blank=fast dev=/dev/sr0

With 2.6.23 this happens:

wodim -blank=fast dev=/dev/sr0
Device type    : Removable CD-ROM
Version        : 5
Response Format: 2
Capabilities   :
Vendor_info    : 'BENQ    '
Identification : 'DVD DD DW1640   '
Revision       : 'BSRB'
Device seems to be: Generic mmc2 DVD-R/DVD-RW.
Using generic SCSI-3/mmc DVD-R(W) driver (mmc_mdvd).
Driver flags   : SWABAUDIO BURNFREE
Supported modes: PACKET SAO
HINT: use dvd+rw-mediainfo from dvd+rw-tools for information extraction.
Speed set to 5540 KB/s
Starting to write CD/DVD at speed   4.0 in real BLANK mode for single session.
Last chance to quit, starting real write i   0 seconds. Operation starts.

and it blanks a rewritable disc, if I do the same thing in 2.6.24rc* it never
gets to the "Speed set to 5540 KB/s" and those kernel errors occur. I'm also
unable to eject the disc from the drive.

Same pattern with k3b, but just opening k3b causes the problem. Before there's
any attempt to even burn a disc it's already jammed up.


Hope this helps, I doubt I'll be the only person who runs into this problem.
