tail -f kernel panic
I found it is quite easy to panic a -current kernel with 2 login windows. In window 1 do a "tail -f /tmp/world.out" In window 2 do a "tail -f /tmp/world.out" In window 2 do "^C" to break out of tail -f In window 1 do "^C" to break out of tail -f The box panic immediately. I can't get a coredump at the moment because the kernel just stops while doing the "syncing disks... 7 7"... Maybe it is related to kern/25309?

Hmm. I reproduced this here; the panic is in SLIST_REMOVE() when it is removing the second event. Funny enough, this does not happen on -stable. Did something change in the list macros recently that would cause this? -- Jonathan To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
