550 reboots without crash, with this patch reverted.
Will try the execute_in_process_context thing now.
I wouldn't bother ... because of the structure, the
execute_in_process_context() patch must have the same bug, but the
context check will make it much more difficult to hit.
Ok, will revert to the -git7 status and poke around once it crashes.
this is struct scsi_target in scsi_target_reap_work()
release = 0xd0000000002190c0}, reap_ref = 0, channel = 255, id = 100, create = 0, scsi_level = 0 '\0', hostdata = 0x0, starget_data = 0x1ffffffec60}
^^^^^^^^^^^^^
This is interesting.. This means that it is on ipr's logical scsi bus (255). Assuming this is
happening at boot time and not due to a user initiated scan through sysfs, this
means we are going through the scsi_add_device path, rather than the scsi_scan_host
path...
