Hi folks,
I'm running a new server with FreeBSD 7.0-RELEASE and am seeing timeouts 
and other messages with mpt0

These include:
mpt_cam_event: 0x16, 0x12 & 0x60

More importantly these:
Dec 28 16:33:30 ted kernel: mpt0: request 0xc68db554:44729 timed out for 
ccb 0xc691f000 (req->ccb 0xc691f000)
Dec 28 16:33:30 ted kernel: mpt0: request 0xc68d8bc4:44730 timed out for 
ccb 0xc6ac1c00 (req->ccb 0xc6ac1c00)
Dec 28 16:33:30 ted kernel: mpt0: attempting to abort req 
0xc68db554:44729 function 0

Dec 28 16:33:30 ted kernel: mpt0: completing timedout/aborted req 
0xc68d8328:44731
Dec 28 16:33:30 ted kernel: mpt0: request 0xc68d5ac8:0 timed out for ccb 
0xc6af4000 (req->ccb 0)

I have raised this with my provider and they have said "it is working 
fine without any problem you can simply ignore this message".

Now I'm no expert on the megaraid controller but I'm fairly certain that 
frequent timeouts are not something that I want to be seeing. I looked 
around and saw other people asking the same but no answers posted 
publicly. I was also wondering as to whether linux emulation could be 
used to run the LSI Megaraid storage manager or whether attempting to do 
so is a very bad idea..

Thanks,
