mpt0: QUEUE FULL EVENT: Bus 0x00 Target 0x04 Depth 129

Hi All,

I'm trying out -CURRENT on an IBM HS21 blade. So far the machine looks stable.
Only thing that bothers me is the message as stated above.

db46-23-freebsd# uptime
11:25AM  up 55 mins, 5 users, load averages: 0.01, 0.90, 1.21
db46-23-freebsd# dmesg | grep -c "QUEUE FULL EVENT"

db46-23-freebsd# uname -a

db46-23-freebsd#

Is this something to worry about?

The LSI Logic controller in question is configured as a hardware RAID-0
Informations about the controller:
at boot time from dmesg:

PS.: FWIW, Linux 2.6.20 had severe problems with this specific mpt controller - patches came with Linux 2.6.21
Looks like the LSI Logic stuff isn't very well supported. On the other hand, there's now way around them when using IBM blades :(
Same counts for the bce(4) NIC.
