Just for grins, I updated a test system to 10.00 and retested, and was
able to reproduce the issue with:
mpt2sas1: LSISAS2008: FWVersion(10.00.02.00), ChipRevision(0x03), BiosVersion(07.17.00.00)
I added the code below to the end of _scsih_sas_device_status_change_event():
printk(KERN_ERR "%s: %s handle 0x%04x sas address 0x%016llx dev %p priv %p\n", __func__,
event_data->ReasonCode == MPI2_EVENT_SAS_DEV_STAT_RC_CMP_INTERNAL_DEV_RESET ?
"internal device reset complete" : "internal device reset",
le16_to_cpu(event_data->DevHandle), (unsigned long long)le64_to_cpu(event_data->SASAddress),
sas_device, target_priv_data);
and when I hit the issue, I got the output below -- the thing to
notice is that we get "internal device reset" events for every handle
in the range 0x24 ... 0x3a inclusive, but the "internal device reset
complete" event for handle 0x2b never appears in this case.
So if this is a firmware bug, it is still present at least in the
10.00 firmware I got from the LSI web site...
This reproduction took about 50 loops of a script that turns off and
on the links between the HBA and the JBOD every 15 seconds, so it's
not too hard to hit (you can see from the kernel timestamps that the
system was up less than half an hour total). If there's any other
debug data to collect or patches to try, I'm happy to do so.
