For explaining - I have changed some points:
I removed the trace in the clock int.
I exchanged the texts for the swi clock thread (pid 12).
That was neccessary because the thread run longer than it take to
get the next schedule with big texts.
, means scheduling pid 12
. means running pid 12 (for loop in sithd_loop)
.d means pid 12 sithd_loop done
.l means pid 12 sithd_loop (while loop in sithd_loop)
.r means pid 12 sithd_loop resumed
Sometimes I'm getting the irq of sym0 and sometimes I get an int from
sym0 and sym1 but after that neither the swi clock nor one of the sym
ithreads is running...
The fact that the clock swi is still scheduled means that the clock int
must be still working.
The disabling of the sym ints work because if I remove them it gets
refired at once like it should.
Without ktr I usually see errors from some scsi drives that don't understand
some probing commands. The errors itselfes are OK because cam falls back
to a traditional mode but it tells me that it hangs later.
I wonder if it may have something to do with the keyboard driver which was
noticed as problematic on i386 recently.
I have no keyboard plugged in but still compiled the driver into the kernel.
As you can see the probing fails.
I also wonder how the mutexes like Giant and sched_lock can work from
int mode. AFAIK the int itself doesn't have a context of it's own.
