#836 Storage wizard crashing

[Lorio]

OS Version: FreeBSD 8.2-PRERELEASE
Platform: Intel(R) Atom(TM) CPU D510 @ 1.66GHz / Supermicro MBD-X7SPA-HF-0
FreeNAS Build: FreeNAS-8r5742-i386

The last three released beta versions showed the same behaviour.

When clicking the "Storage Wizard" Button to add a volume the following error occured:

Update: After upating the BIOS of Supermicro MBD-X7SPA-HF-0 to C31 the problem of scanning the sata disks is gone (If you have similar problems just boot FreeNAS with the reporting option to see proper error messages. Often a device is not found and the web gui crashes without proper hint what really happend).

Still unclear if a bug in the bios was causing that problem or the reset to the default settings helped fix it.

I could pinpoint the error to the memory card reader.

FreeNAS/FreeBSD is trying to open the memory card reader, when the medium is not present / it didn't worked with a inserted medium either.

"Opened disk da2 -> 6"
(da2:umass-sim1:1:0:1): SCSI status error
READ CAPACITY(10). CDB: 25 20 0 0 0 0 0 0 0 0
CAM Status : SCSI Status Error
SCSI status: Check Condition
SCSI sene: NOT READY asc:3a,0 (Medium not present)
Error 6 , Unretryable error

When deconnecting the memory card reader from the mainboard the wizard will show all attached harddisks.
