Changes

This particular problem involves Qlogic QLA2340 card, installed in an X4200 and possibly an X4100 server
This issue is not present in the M2 variant of the platform.

Cause

The AMD 8131 bridge chip found in the X4200 and X4100 platforms cannot handle large successive packet transfers simultaneously through high performance fibre cards such as these.
<SUNBUG: 6426312>, <SUNBUG: 6534498>, <SUNBUG: 6483985>, <SUNBUG: 6399981>, <SUNBUG: 6531645>, <SUNBUG: 6532156>
See also <Document: 1000551.1>

Solution

Move the card to a higher speed PCI-X slot.
X4200 server has 133MHz and 66MHz slots, once the card is moved to 133MHz slot, the problem does not reoccur.

Other alternative that will work:
If card is in PCIX-66, change pci-max-read-request=1024

This parameter is in the qlc.conf file:

cd /kernel/drv
cp qlc.conf orig.qlc.conf
edit qlc.conf file and change
pci-max-read-request=2048;
to
pci-max-read-request=1024;
