This is a siis(4) card -- chances are he can't turn it off. :-) We
really need a backtrace to see what transpired.
The siis(4) driver may have crashed as a result of LUN timeouts. The
driver shouldn't panic, I agree, but the port timing out is of major
concern. I imagine this behaviour (the crash) could be reproduced even
if UFS2 was used and the timeout took place.
