I guess there will only be a chance if somebody else can reproduce the bug, unless you are able to try debugging it yourself. Try the following: Before it's crashing, enter dumpon /dev/sd0b as root. This will enable kernel core dumping. After the crash, the kernel will save a copy of its image under /var/crash at the time of reboot. After the system came up again: gdb -k /var/crash/*.0 and once you see the (kgdb) prompt: where Tell us the output of this command. (I'm also trying to have a friend running a box with 6 CD drives reproduce this.) -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ Never trust an operating system you don't have sources for. ;-)
