>Description:
I recompiled and installed world + kernel this morning (Sun Oct 10 CEST 2004).

I mounted a data cd, unzipped one 200 Mb file, umount'd that cd, and then mounted it again getting a kernel panic.

/sbin/mount and /sbin/umount are owned by root:wheel and 'chmod +s', but I use these commands with my normal user vyger:vyger,wheel

Immediately after the "acd0: WARNING - removed from configuration" message, the kernel panics.

that's my /var/log/messages:

>How-To-Repeat:
However, I think TIMEOUTs and FAILUREs are hardware-related problem.
I was not able to reproduce the bug due to the fact that after this error I always received an I/O error mounting the same cd (I also think that the cd is not burned correctly, or - better - the rwcombo is not high quality).

hope this helps!
