Hi Sven, hi Martin, hi all
it’s me again. After 11 minutes in gw mode the VM crashes again. The
“attacker” is back. Its your chance for new patches ;-) I disable
fragmentation, lets see if it helps.
I think I might did a mistake. The kernel is compiled with gcc 4.7.3,
the patched module with 4.8.3. On the next crash I recompile the module.
Best regards
Philipp
