0006276: Kernel 2.6.32-358.0.1 fails to reconnect Fibre Channel drives after fc loop disconnection

After kernel update to version 2.6.32-358.0.1 it is no longer possible to connect/turn on a fibre channel drive and have it recognized by the system once the system is up and running (after bootstrap) as it was up to kernel-2.6.32-279.22.1: with kernel 2.6.32-358.0.1 the drives fail to connect and the following errors are recorded in /var/log/messages:<br /> <br /> Feb 28 23:02:16 sirius kernel:
