Re: Xen kernel broken for me

[Roger Pau Monné <roger.pau%entel.upc.edu@localhost>]

I've filled a pr the past month, some of the recently merged branches
broke the dom0 xen kernel, here is the bug report:

http://gnats.netbsd.org/cgi-bin/query-pr-single.pl?number=45062

Take a look to see if it's related.

Regards, Roger.
