Hello,

I've been testing with the qla2300 driver with 2.6.14.3 and 2.6.15-rc4.
I've observed two sets of error messages which are not present with
2.6.14.3.

First, the qla2300 driver is generating soft lockups.
Second, several error messages indicating that remote
ports are being deleted are being emitted.

 rport-2:0-16: blocked FC remote port time out: removing target and saving binding
 run_workqueue: recursion depth exceeded: 29

If the timing is just right, scsi errors are generated, though not evident
in the attached dmesg file.

I've observed similar behavior with my modified mpt fusion driver
when multiple hba ports are on the fabric.  The kernels tested
are as downloaded from kernel.org, without my mpt mods.

(Andrew, I'm not "blaming" your driver for the rport issues.  I chose
your driver to be the "victim" 'cause I didn't want to post this using
under development code with mpt fusion.)

Platform: SGI Altix IA64.

What additional information should I acquire?
