Re: [Xen-users] panic in XenU 7503:20d1a79ebe31 reading from network

[Thomas Schneider <etomsch@xxxxxxxxxx>]

Hi,

I got the same problems here. I already tried to rebuild my gcc without ssp 
and pie and rechecked all my kernel-configs but couldn't find anything 
wrong.
The machine this should be working on is an AMD64.

Unfortunately, I couldn't find a solution yet.

Thanks in advance,

Tom
