FC HBA not working anymore after upgrade to SLES 11 SP4
i have a HP ProLiant ML 350 G6. Using SLES 11 SP3 everything was running fine. I have a FC HBA (Emulex LPe11000 PCIe) which connected the server to a FC SAN, this worked without any problems. After upgrading to SLES 11 SP4 i get constantly these errors in /var/log/messages:

I don't have a connection to the SAN anymore. Also installing the newest kernel from SuSE did not solve it.
I can reproduce the error with a new clean installation of SP3 and updating to sp4.
Also exchange of the FC HBA to a HP AJ763 did not solve the problem.
I booted the server with a knoppix dvd, then the connection to SAN was ok.
