hi,
last evening i put in a cd-rw in my cdrw-drive (IDE), and automount (triggerd by some gnome-filemanager) was about to mount it. it did not succeed, the drive-LED was on "busy", mounting was not possible, but the system otherwise stable. "killall -9 mount" did not succeed, neiter did "SYSRQ+S|U" after trying to reboot, ok, i had to "SYSRQ+B" then. i never had this before, after reboot i could successfully access my cd-rw, so the bug is probably not reproduceable. afterwards i saw this in my log (appended). yes, the kernel is TAINTED (nvidia module), and since the bug only occured one time, it's probaly not worth to mention it at all. but perhaps not and that's why is post this :-)
system is x86(amd900), kernel is 2.6-BK (updated a few days before). so, here's the log:
