Comment 2 Zing 2005-02-16 17:28:05 EST
ok, the scsi card is really a 2940A Ultra card.  Sorry about that... so I tried
the aic7xxx_old driver and I still get unknown opcodes and a bunch of new type
of errors such as data overruns detected, BUT I can actually burn a cd now and
it works.

i guess this isn't so much an issue untill the _old driver goes away.

Comment 5 Dave Jones 2005-07-15 13:40:06 EDT
An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which
may contain a fix for your problem.   Please update to this new kernel, and
report whether or not it fixes your problem.

If you have updated to Fedora Core 4 since this bug was opened, and the problem
still occurs with the latest updates for that release, please change the version
field of this bug to 'fc4'.

Thank you.
Comment 6 Zing 2005-08-01 11:54:53 EDT
fc4, 1398 kernel, aic7xxx, still fails in the same way as in comment #1.  (A
firmware update to 1.05 of the cdrw didn't help.)
Comment 7 Aaron Kaplan 2005-08-15 10:20:59 EDT
I get the following uknown opcode errors when burning with cdrecord on an ATAPI
Plexwriter 24/10/40A with kernel-2.6.12-1.1398_FC4.  It's the same as reported
above, plus 0xF5.

kernel: scsi: unknown opcode 0xe9
kernel: scsi: unknown opcode 0xed
kernel: scsi: unknown opcode 0x01
kernel: scsi: unknown opcode 0xf5
kernel: scsi: unknown opcode 0xeb

The burn fails, and cdrecord hangs and can't be killed.
Comment 8 Dave Jones 2005-09-30 02:08:48 EDT
Mass update to all FC4 bugs:

An update has been released (2.6.13-1.1526_FC4) which rebases to a new upstream
kernel ( As there were ~3500 changes upstream between this and the
previous kernel, it's possible your bug has been fixed already.

Please retest with this update, and update this bug if necessary.

Comment 9 Zing 2005-10-03 15:36:52 EDT
still fails with 2.6.13-1.1526_FC4.  I'll attach a new full dmesg log and an
lspci  dump

Comment 12 Aaron Kaplan 2005-10-09 04:57:31 EDT
I confirm that this has not been fixed by 2.6.13-1.1526_FC4.
Comment 13 Dave Jones 2005-11-10 14:07:00 EST
2.6.14-1.1637_FC4 has been released as an update for FC4.
Please retest with this update, as a large amount of code has been changed in
this release, which may have fixed your problem.

Thank you.
Comment 14 Aaron Kaplan 2005-11-12 07:31:30 EST
Under 2.6.14-1.1637_FC4 the "unknown opcode" messages still appear in the log,
but I am able to burn a CD again.
Comment 15 Zing 2005-11-14 10:43:59 EST
Confirmed! Under 2.6.14-1.1637_FC4 I can burn cds again.  My logs are very clean
too... no "unknown opcode" messages showed up for my setup.
Comment 16 Dave Jones 2006-02-03 00:13:13 EST

based upon a new upstream kernel release.

Please retest against this new kernel, as a large number of patches
go into each upstream release, possibly including changes that
may address this problem.

Comment 17 Zing 2006-02-06 09:44:00 EST
Unfortunately, I no longer have the hardware to test the cd writing under
2.6.15.  In case you missed my note in #15, it worked fine under
