ide-scsi scheduling while atomic in linux-2.6.0-test11
From: Bart Samwel
Date: Wed Dec 10 2003 - 00:31:47 EST
[1.] One line summary of the problem:
ide-scsi scheduling while atomic in linux-2.6.0-test11
[2.] Full description of the problem/report:
ide-scsi gives me "scheduling while atomic" while burning a CDRW in
linux-2.6.0-test11, when an interrupt is lost. I have no clue what
caused this; I was writing a CDRW that might have been faulty, but
otherwise nothing unusual. The CDRW is a Samsung SW-408B on the
secondary slave. While burning, I was extracting audio data from a CD in
the DVD player that was on the secondary master.
[3.] Keywords (i.e., modules, networking, kernel):
ide-scsi, cd-writing
[4.] Kernel version (from /proc/version):
Linux version 2.6.0-test11 (root@xxxxxxxxx) (gcc version 3.3.2 (Debian))

[7.6.] SCSI information (from /proc/scsi/scsi)
Not very useful when I've already removed ide-scsi from the system. :(
It says no devices are attached. D'oh!
[X.] Other notes, patches, fixes, workarounds:
If you want to know if the ATAPI interface works any better, I'll be
trying this for now so please mail me if you want to know.
