- - I got another one:
sdstart(): dequeued wrong buf
scsipi_put_xs()
scsipi_complete()
scsipi_done()
ncr53c9x_done()
ncr53c9x_intr()
hmmm..i don't have any disks or cdrom in my sparc box..
hmm, it took an interrupt in uvm_fault_internal() - is that supposed
to happen?
Also, the MP kernel made it all the way through filesystem checks /
log replays and only crapped out when sshd started.
Any idea what's happening here?
Maybe something fails to grab the kernel_lock ?
Can you add a check (KASSERT or something) that the kernel_lock is
held in ncr53c9x_intr() and ncr53c9x_scsipi_request() ?
Maybe something like
KASSERT(__SIMPLELOCK_LOCKED_P(kernel_lock)
or
KASSERT(ci->ci_biglock_count > 0)
will work to check this.
