Bug#395390: wodim: cdrecord -checkdrive freezes with CyberDrv CW088D

[Eduard Bloch]

reassign 395390 kernel
retitle 395390 IDE driver (via?) freezes ignoring ATAPI timeout
severity 395390 important
thanks

Unfortunately I don't know a good way to continue with debugging it. I
am reassigning your issue to the kernel team.

Eduard.

This looks like a kernel bug. I assume that your drive freezes, and the
driver does not abort, ignoring the requested timeout.

Ok. Seems like a longstanding bug then since I pretty sure it was
already present in 2.6.13. Would you happen to know of kernel debug
options to turn on to get more data? Or hints as to where I should dig
(this is a standard IDE CD writer and a VIA 'VT8375 [KM266/KL266]'
chipset).

A couple more notes: I used to be able to write CDs with this burner. I
am sure it worked with a 2.4 kernel. It may have stopped working when I
switched to a 2.6 kernel, a long time ago.

Could you make the wodim binary suid-root and retry the same thing?

Actually I ran the above command as root (to match xcdroast which I runs
it as root).

This is where cdrecord freezes and thus where the traces end.

It waits for the kernel to return. A program cannot abort a syscal just
so, so it's kernel's turn, no matter what the outcome is.

Yes, that does seem to point to the kernel.
