I am using the Xen version that comes with FC5 (although this has also
happened on FC4 and CentOS 4.2 with other versions of Xen), and am
having a problem with the kernel constantly oopsing in a similar way.
Here is one of them:

These oopses *always* have either "vfs_stat_fd" or "vfs_lstat_fd" at the
top of the call trace. Does anyone know why this might be? If it is
any help here is the output from lspci so you know what hardware I have
(it is a SuperMicro motherboard):

Could someone pleeeease help me with this it's driving me crazy!
