I'm running into the same problem, mpt(4) panic on FreeBSD 8-STABLE.
I'm running FreeBSD 8.0-STABLE, the current kernel was cvsup'd and built
@ January 14th, 2010. I cvsup'd tonight, 2/25/2010, and built a new
kernel. Attached is the panic when I tried to boot into single user
mode, I was able to boot up on the old kernel built on January 14th.

Attached patch should fix the problem.

Re: Panic on 8-STABLE in mpt(4) on a DELL PowerEdge R300
COOL! THANKS a LOT Alexander! Can't believe it. You post a panic at 11pm and get a patch at 1pm next day...? You must be crazy! ;) Works for me. I patched against 8/stable. I'll be testing the machine a bit more. But for now, no panics! I guess the patch should be committed soon, also because it's really happening quite at beginning, without a RAC/ILO you're locked out pretty fast, and mpt is used on many DELL/HP setups. while true ; do echo Thank You ; done Lorenzo On 26.02.10 13:25, Alexander Motin wrote: John J.

The controller is the SAS 6i/R. If I can provide any other details please let me know. Thanx a lot for taking your time, A follow up - I recompiled the kernel with mpt from head (svn checkout svn://svn.freebsd.org/base/head/sys/dev/mpt) and the problem still exists. Let me know if I should post a pr. I'm also available for testing patches.
