Description Mark McLoughlin 2008-02-21 13:44:28 EST
With a Xen guest on rawhide using this pv_ops based kernel:


we get this segault in kudzu:

  Program received signal SIGSEGV, Segmentation fault.

notting's comment on this a while back was:

    <notting>       oh that's right. the code probing for ancient pre-cardbus
pcmcia controllers
    <notting>       hm, that can probably be taken out ;)
    <notting>       especially because we build them in

Will be solved one way or another.
