Subject: Xen killing my e1000s?
Date: Fri, 11 Dec 2009 15:36:33 -0800	[thread overview]
Message-ID: <4B22D781.5090704@goop.org> (raw)

I have this Xeon 3430-based system with a pair of on-board PCI-e 
e1000s.  When I'm running under Xen, they disappear in use.  That is, 
the PCI devices themselves seem to give up the ghost, and lspci -x shows 
all 0xff for their config spaces. They come back to life when I reset 
the machine.

When I boot under native Linux all seems fine.

I'm running with VT-d and all the other features enabled; I haven't 
tried turning them off yet.  There are no obvious messages from the 
kernel or Xen complaining about anything.

This is a new machine, so it could be an outright hardware problem, but 
it seems like an odd failure-mode for a hardware fault (I'd expect 
on-board devices to either work or not work, and not come back on reset).

Anyone got any ideas?

Thanks,
     J
