Re: Xen41 dom0 panic when downloading iso with wget

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

Hello,

Thanks for the information, I've already committed a PR at
http://gnats.netbsd.org/cgi-bin/query-pr-single.pl?number=45051 but
it's my first time using NetBSD and I'm not really sure if it's the
best place, and if it has all the necessary information. Also the
problem only happens when using Xen, I've tried the same kernel (a
GENERIC version of course) and it runs fine.

Regards, Roger.
