 I can reproduce this, so I'll look into it.  It's related to the /dev/mem
"test"
 to determine whether the kernel was configured with CONFIG_STRICT_DEVMEM, where
 it tries to read from pfn 257 (just above the CONFIG_STRICT_DEVMEM limit), but
 gets into an infinite loop when used in conjunction with -d.   
 
 Anyway, just continue to use /proc/kcore and you should be fine. 
I assume switch_to_proc_kcore() isn't Xen specific but since it will
happen on all our dom0's would you care if I continued with it?
