-current silent lockups

Hi,

I have a -current box that is behaving badly.  My main suspicion is
that the hardware is flaky, but Google searches on the error code
reveal that Linux had a software bug that caused this same issue.  So,
before I argue with Dell, I thought I'd ask here to see if there's any
chance FreeBSD has a similar error.

The system is a Dell 2850, with 6 300GB disks in hardware raid 5.

The error occurs randomly.  The machine locks up; keyboard is
nonresponsive, console continues showing the same thing.  Ctrl-Alt-Esc
does nothing.

Under normal use, every couple of weeks the box locks up like this.

When I kldload ipmi.ko, the lockup occurs daily.

When I attempt to boot a fresh -current GENERIC kernel on this system,
the system completes a single-user-mode boot but never completes a
multiuser mode boot.  (It's a slightly older -current, so I thought an
upgrade might be useful; but I don't want to run the installworld if
it's going to do nothing but lock up!)

Is there any chance this is a FreeBSD bug, and not a Dell hardware
problem?  This box is not in production yet, so I can beat the crap
out of it for the next month or so.

Any advice appreciated!  System info follows.

Thanks,
==ml
