Hi all,
We enountered an unusual condition with the LSI SCSI drivers last night
- we got an "attempted task abort", followed by about 10 minutes of no
messages (I wasn't logged in at the time but believe the system was
unresponsive), followed by several minutes more of similar messages,
repeated:

(... etc)
This is on a dual opteron 1.8Ghz Tyan system, running a fairly minimal
FC5 install.
The problem resolved itself after a little while, but the web server
became unresponsive during this time - obviously it looks like some kind
of loop in the LSI kernel module - has anyone seen anything like this
before? It looks like something to report to the linux-kernel or
linux-scsi mailing lists, but as I'm using FC5 I thought I'd ask here first.
Thanks in advance,
