5.4-STABLE from 5/27, repeated panics. Finally got a crashdump, fired up kgdb and:
(is there any advantage to booting the kernel.debug instead of the regular kernel? Can't think
of one, but possibley...).
The box does run several jails. It has been crashing regularly under both 5.3-RELEASE and now 5.4-STABLE.
Apps are all mysql/apache/mail apps, nothing fancy.
Disk controller is an adaptec using the asr0 driver, and it is a dual Xeon compiled with SMP suppo0rt.
s1# kgdb kernel.debug /home/crash/vmcore.0
