Are you positive?  When we switched to the sym0 driver, these "Weird
Shit(TM)" panics went away.  The machines that the sym driver is
running on are under high disk load and have been stable for days
rather than hours with the ncr driver.

Do you have any way to easily reproduce it?  I can put a lot of
resources to tracking this down, if you have some way of easily
reproducing the panic.
