Xen 2.0 xennet_watchdog

["Florian Heigl" <Florian.Heigl%gmx.net@localhost>]

hi,

I just wanted to inform You that I had the pleasure of meeting 
the xennet_watchdog error during install.

hard disk is sliced and partioned, the error occurs when trying to 
DHCPdiscover on the xm virtual interface. I'm not sure if the bridging 
is properly set up by me, but still the panicking is annoying :)

I'm using netbsd-INSTALL_XENU from

ftp://ftp.netbsd.org/pub/NetBSD/arch/i386/snapshot/20050408-3.0_BETA/binary/kernel/
on Xen 2.0.4 (on a Linux host - see below for more specific data)

hmmm - I'd be very happy for some pointers, i.e. that this will be
resolved if I upgrade the Xen version I use. :)

---with further testing I noticed that this will also happen,
if I just ifconfig---
