Sure does, but how does one recover from a hardware lockup ?
Well say the PCI buses timing gets hosed and the whole system seizes up what do you intened to do at that point (that is a hardware lockup)? And what does that thing you do have to do with debuging a kernel? Just curious.
Even if it were possible to have that kind of debugging, it would be fairly limited.
When you say "hardware" I start thinking jtag interfaces, or even more interesting was this thing we would place every pin of the processor through and then connect to the socket on the motherboard, but I think I missing something. Cheers...james
