(This was immediately after the crash, hence the filesystem warnings...)
`kldstat` shows kernel, and acpi.ko are loaded
Kernel compiled with
options SMP
options IPFIREWALL
options IPFIREWALL_VERBOSE
options DUMMYNET
options HZ=1000
It must be noted that freezes also occured on the non-SMP GENERIC kernel(before I'd done the recompile)
Tried putting system under load to repeat problem, with the following:
`cd /usr/src`
`tar cfz ../hog.tgz *` (to simply put CPU and HDD under load)
No effect.
Put CPU and kernel process queue under more load with some simple c++:
#include <iostream>
main() {
while(1)
{
// Do a tight loop of nuthin
}
return 0;
}
and launched 50 of them - no effect
Then re-launched tar as well to strain disk subsystem. `top` output now:

Next test: leave it idle for a while
Well, I've had four coffees, and I'm getting tired of waiting...submitting this PR.
