ok, some progress: managed to reproduce the jackd instant lockup on my
P4 HT SMP box. (hacked my kernel to ignore the second CPU's ACPI entries
so that i got a single-physical-CPU HT setup. The box has the same i8x0
sound stuff as your box.)
not much debug info yet, but it's not a classic hard lockup. It rather
seems to be jackd (or the kernel) looping indefinitely. Keyboard doesnt
work because it's threaded by default ...
more later.
