Oops, missed that.  I'll see whether there's IRQ storm going on.
I made the nv irq handler to print message every 100th time and it says
nothing after lock up and no response to keyboard, sysrq or serial.  It
seems like a solid lock up to me.  Anything else you want me to try out?
I assume that replugging or unplugging cables after that point doesn't
bring it back to life?
Nope.  The machine is a solid brick.

If you want, I can ship the board + processor + cooler to you for
debugging.  I guess it will be more useful in your hands than mine.

If it's an A8N-E I'd be surprised if it behaved differently from my A8N-SLI Deluxe, though maybe it's a different chipset revision or something.. The last time I tested hotplug on here it seemed to work fine, though I haven't done any rapid disconnect/reconnect tests.

How about putting a bunch of printks inside the interrupt handler? That would tell us if it's even reaching the interrupt handler..
