In experiments in the lab we managed to trigger an Adapter firmware panic (BlinkLED) coincidentally while several pass-through ioctl command from the management software were outstanding on a bug only present on a class of RAID Adapters that require a hardware reset rather than a commanded reset. The net result was an attempt to time out the management software command as if it came from the SCSI layer resulting in an OS panic. Adapters that use commanded reset, management commands are returned failed by the Adapter correctly. The adapter firmware panic that resulted in this condition was also resolved, and there were no adapters in the field with this specific firmware bug so we do not expect any field reports. This is a rare or unlikely corner condition, and no reports have ever been forwarded from the field. This attached patch is against current scsi-misc-2.6.
