zfs discuss - May 2010 - scsi messages and mpt warning in log - harmless, or indicating a problem?

This afternoon, messages like the following started appearing in
/var/adm/messages:

May 18 13:46:37 fs8 scsi: [ID 365881 kern.info] /pci at 0,0/pci8086,29f1 at

The pool has no errors, so I don''t know if these represent a potential
problem or not.

During this time I was copying files from one fileset to another in the same
pool, so it was fairly I/O intensive.  Typically you get one every 1-5 seconds
for 10 to 20 seconds, sometimes longer, and then it is quiet for many minutes
before they occur again. Is this indicating a problem, or just a harmless
message?

I just kicked off a scrub on the pool as I was writing this, and I am seeing a
lot of these messages. I see that zpool status shows c4t5d0 has 12.5K repaired
already. The scrub has been in progress for just 6 minutes, and it says I have
170629h54m to go, and it gets longer every time I check the status. I ran a
scrub on this a few weeks ago, and had no such problem.

I also see two warnings earlier today:

May 18 19:14:09 fs8 scsi: [ID 243001 kern.warning] WARNING: /pci at
0,0/pci8086,29f1 at 1/pci15d9,a680 at 0 (mpt0):

IOCLogInfo=0x31110900
May 18 19:14:09 fs8 scsi: [ID 243001 kern.warning] WARNING: /pci at

May 18 19:14:09 fs8     mpt_handle_event: IOCStatus=0x8000,
IOCLogInfo=0x31110900

and two more of these 1 minute and 10 seconds later. 

So, is my system in trouble or not?

Particulars of my system:

% uname -a
SunOS fs8 5.11 snv_134 i86pc i386 i86pc

The hardware is an Asus server motherboard carrying 4GB of ECC memory and a
current Xeon CPU, and a SuperMicro AOC-USASLP-L8I card (it uses the 1068E) with
8 Samsung Spinpoint F3EG HD203WI 2TB disks attached.

Welcome to the mpt driver / firmware / something bug! I forget if your 
symptoms were indicative of the card not liking the drives (Hitachis in 
particular, which I fixed by upgrading to larger Seagates) or an issue 
with MSI support (which I fixed by adding "set xpv_psm:xen_support_msi = 
-1" to /etc/system, but I was running a Xen enabled kernel).

I suggest searching the list archives.
