Crashing with HP/Compaq DL360 G3 [paging kernel developer]

Your broadcom is one of the problem chips, you can probably see
the workarounds in the driver.  So I would not rule out a problem
with the ethernet controller.  If you have money to burn on this
then install an Intel pci express or 64 bit pci card and disable the
onboard ethernet chip and see what happens.

However what you really need to do at this time is get your
seemingly-random panics to become repeatable.  We start with
the assumption that this is a hardware problem.  PC's in general
have 4 areas of hardware that cause problems:

disk IO

sometimes video is a problem but you can check for this
by simply not logging into the console and doing all your access
over the network.

What you need to do now is go into the ports directories
and build some of the stress-testing utilities then run them.
Start by running a disk stresser, see if that causes it to panic.
Next run a network stresser, see if that causes a panic, next
run a cpu stresser, etc.etc.  I think you get the idea here.  What
we are trying to do is find a program that can cause the system
to panic on demand, that is a program that really mostly does
only 1 thing, either disk, network, memory, etc.

Once you got that then you can start hardware substitution on
the affected area (if possible)
