Re: kernel panic on em0/taskq



I just checked the link you have reported.
It looks like the problem is present only on SMP machines with both
ULE and 4BSD scheduler.

I can confirm that the problem is also present on 6.3-Stable.

Basically, it freezes before collecting dump and before being able to reboot.

I wish i could have more informations to open a PR.


Thanks,

Daniel

Sorry, I did not read well you suggestion ;)

Anyway, the system reboots correctly if I issue the reboot command from command line.
Should i adjust those values anyway?

I'd recommend adjusting them and see if the bug (not automatically
rebooting on panic) changes.  I'm guessing it won't (especially if
reboot(8) works fine), but it's worth trying.

You're the 2nd person I've seen who has reported this problem (re:
FreeBSD not properly rebooting on panic).  The other person:

http://lists.freebsd.org/pipermail/freebsd-stable/2008-May/042250.html

I'll add this to my Commonly reported issues Wiki.  As for the problem
itself, sorry, I have no idea what's causing it.
