Since the latest ballooning patch "Add hugepage support to balloon

<http://git.kernel.org/?p=linux/kernel/git/jeremy/xen.git;a=commit;h=0e898d5e9b

i experience dom0 console freezes. Additional to that there is a
stacktrace about a kernel-bug in drivers/xen/balloon.c in line 346,
invalide opcode 0000 (i can send the full stacktrace if someone is
interested).

Yes, please.  Presumably its from the BUG_ON testing the hypercall
return status?

This time really with the attachment ...

Thanks.

BTW, it looks like I hadn't merged the hugepage into xen/master until now. Did you merge it yourself? Or trying something else?
