problems with xen and kmodule

On one of my machines, kmodule under xen gets stuck in an infinite loop: rt_sigprocmask(SIG_SETMASK, ~[], [], 8) = 0 vm86old(0x806a94c) = -1 ENOSYS (Function not implemented) rt_sigprocmask(SIG_SETMASK, ~[], [], 8) = 0 vm86old(0x806a94c) = -1 ENOSYS (Function not implemented) .... (I can ^C it, when rc.sysinit starts, causing the script to exit and init to continue to runlevel 3.) Without xen, it outputs the following: OTHER i2c-viapro OTHER parport_pc NETWORK via-rhine AUDIO snd-via82xx USB uhci-hcd USB uhci-hcd lspci: 00:00.0 Host bridge: VIA Technologies, Inc.
