Hello,
After doing much research I have come to the conclusion that the kernel might
be at fault (in conjuction with the mobo) for hard-locking my box. Please
read below to see if you can help me.
I am coming to wits end with this MSI K7D Master-L board. I have narrowed it
down to find that anything that causes alot of interrupts will lock the box.
By lock I mean a HARD lock, no ping, no mouse, no oops, no sysrq, no nothing.
It is a sudden and TOTAL lockup. A ping -f and playing xmms at the same time
will cause the box to lock in minutes while as if there is very little
activity I can run for perhaps an hour or so maybe more (havent had the time
or the patience to baby-sit an idle box for more than an hour. This is my
main box.)
When I ran this box as a single-cpu system with an athlon mp2400 it ran fine.
Perhaps something with SMP is triggering a nasty bug.
The motherboard was bought to replace another motherboard and so I could go
SMP. The ram, powersupply,ALL cards, basically all the hardware are known
good and have been used for months in another system. The LCD here is the
mobo.
I have googled extensivly and have tried many things to see if I can alleviate
the problem, so far nothing. Does anyone have any ideas to see if this is a
kernel problem?
Is this a known problem? Is there a patch to fix this? I am trying to avoid
replacing/returning such a beautiful and expensive motherboard.
Here is excerpt from a Redhat mailing list

So it seems to suggest something in the kernel has something in part to do
with the lockup. Anyone have any suggestions? Any info I can provide?
Here is a non-exhaustive unordered list of various things I've tried.
-Combonations of noapic nolapic acpi=off
-Increasing the vcore slightly
-Downloading and compiling the latest kernel (see uname -a output)
-Recompiled the kernel, ran make clean
-turning DMA off in the bios
-turning DMS off via hdparm
-running without a PATA drive at all (all scsi)
-Removing ALL unneccesary cards
-Removing ALL unnecesary devices (to recude power consumption)
-Disabling USB and removing USB support from the kernel
-Installing sensors and making sure voltages/temps are nominal (they are)
-installed and used irqbalance
-Disable preempt
-Try the onboard lan and a 64bit pci gigabit lan card mutually exclusively
-Removed side-panel and verified heat is not an issue
-Updated to latest BIOS version
