Environment

SUSE Linux Enterprise Server 11

Situation

The xen Kernel fails to load the qlaxxx module and does immediately reboot the system. This issue appears on SLES11 64-bit System after an update of the kernel-*, kernel-xen ( 2.6.27.29-0.1.1) and xen-* (3.3.1_18546_16-0.1.1) packages. With a serial console attached on the system, one can see the following:
