Hello all,
I have 8 machines running 6.2-RELEASE, they're all under pretty heavy
load. All but one is running Dual Opterons on Tyan motherboards, the
other is running 2x Dual Core Xeon, on a Supermicro mb. I am receiving
this panic on all the machines, some of them it happens once a month,
others every few days. The only thing they all have in common now is
they're running 3ware 9550SX SATA RAID controllers, and a PAE/SMP kernel
I have done a lot of searching around and have found other people having
this same issue, but nobody seems to have a fix for it, or the threads
just die eventually. I'm trying to get a dump but they seem to be
corrupted when I try and load them into the debugger. I am going to
attempt to do some online debugging next time I encounter one of these
panic's
Anyway, here is the panic message. I have access to a serial console on
all the machines, and I've enabled the kernel option to drop to the
debugger on panic. Does anyone have any advice, or a fix in regards to
this issue?
Here is the closest thing I got with nm from the instruction pointer:
[root@xxx ~]# nm -n /boot/kernel/kernel | grep c03f60
c03f6050 T _mtx_lock_sleep
-------------
kernel trap 12 with interrupts disabled

Cannot dump. No dump device defined. ### NOTE: I've defined the dump
device now.
Automatic reboot in 15 seconds - press a key on the console to abort
Thanks,
