>>First party detected bus hang>>

If you are current on patches, most important the SCSI patches, you want to report this to hardware support as it indicates a hardware problem with the bus.

[Bill McNAMARA_1]

The problem is on the bus with instance 0,
You may have hardware entering into a failing state.. or not followin power on/off recommendations.

ioscan -fnkCext_bus

Your ext_bus with instance 0 has h/w with a problem.
Verify cables and power to these devices.
(don't hot plug scsi)

Later,

Verify SCSI termination.
