Hum, nasty, nasty. Looks like the amount of interrupts caused by
high-speed burning might trigger a race condition between two
instances of camisr(). camisr() does splcam(), but maybe this is not
sufficient to correctly prevent concurrent execution when interrupts
from the ATA driver occur. Maybe the freebsd-scsi people will have a
clearer idea of what is going on here.
