Re: [Xen-devel] domU crash with kernel BUG at drivers/net/xen-netfront.c:305

[Vasily Evseenko <svpcom@xxxxxxxxx>]

I've found workaround:
Run  "ethtool -K vifX.Y  tx off tso off gso off"
on dom0 side (in addition to "ethtool -K eth0 tx off tso off gso off"  
on domU).
Disabling offloading only in domU is not sufficient.
