Hmm, I haven't tried with megacli, but an internal tool at work is able to start manual patrol reads w/o causing a crash, and I've also seen production boxes running automatic patrol reads w/o causing crashes. Do you have to have a certain load before it will crash? > > mif0: COMMAND 0xffffffff892bc998 TIMEOUT AFTER 45 SECONDS > > > > The first 8 values of the hex never change - I bring that up because I > > suspect the problem has something to do with the enclosure, which is > > attached at 8, 255, or fffffff, depending on where you're looking. No, the value is a pointer to the in-kernel command structure. FWIW, I've seen this message with MegaCli with other commands (like removing a volume), so this may have to do with our support for MegaCli. In the case of -LdDelete though, I didn't see an OS crash. However, I've only seen that during testing and would reboot the box once it went south (I also wasn't using any mfi(4) volumes for the base system at the time). -- John Baldwin
