[Xen-devel] Linux 3.11.1 HVM guest kernel crash when started with xl (get_free_entries)

[Pasi Kärkkäinen <pasik@xxxxxx>]

Hello,

Fedora 19, Xen 4.2.3 rpms from the distro.

Starting F19 HVM guest with xl causes the guest to crash during boot.
Starting the same guest with xm/xend works OK.. 

Kernels tested in the guest: 3.11.1 and 3.9.5, both show the same 
crash/traceback:
