acpi related, but on freebsd 4.11 (cvsupped and built on 24 march).
i've compiled with device acpica in the kernel, but i get sporadic page
faults as attached.
i do know that acpica is experimental and that LINT does warn of kernel
panics and machine hangs. however i was wondering if anyone has got this
working succesfully on any machine.
gdb trace of the kernel crashdump reveals:

the segment of code in tsleep() kern/kern_sync.c says,
s = splhigh();
if (cold || panicstr) {
/*
* After a panic, or during autoconfiguration,
* just give interrupts a chance, then just return;
* don't run any other procs or panic below,
* in case this is the idle process and already asleep.
*/
splx(safepri);
splx(s);
return (0);
}
so tsleep() catches the panic and tries to return(0). question is, why is
AcpiOsSleep() borking on it's tsleep(&dummy, 0, "acpislp", timo) call ?
i've tried replacing the tsleep() in AcpiOsSleep() with DELAY(microseconds)
instead, and it works. however this isnt an ideal fix as the CPU isn't
relinquished by a DELAY() like a tsleep() does.
is there another kernel sleep() call i can use, since AcpiOsSleep() just
needs to sleep and not wait for events ?
the box in question is a Benq Joybook 6000 with the following dmesg
segment:
