I'm still getting this periodically on bento. The latest one is:
Fatal double fault:
eip = 0xc0276b13
esp = 0xdfd14000
ebp = 0xdfd1408c
mp_lock = 01000079; cpuid = 1; lapic.id = 00000000
panic: double fault
mp_lock = 01000079; cpuid = 1; lapic.id = 00000000
Debugger("panic")
and the machine hangs there (it always does when I have DDB in the
kernel). I'm going to have to upgrade bento to 5.0 unless anyone can
offer any advice.
