Try turning it off. 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. -- | Jeremy Chadwick jdc@parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
