New kernel oops with 2.8.38/x86/Ubuntu Natty

Postby kecsap » Mon Jul 18, 2011 3:26 pm

Hi,

I installed the vpncclient following this post because I got some kernel oops: viewtopic.php?f=15&t=1293#p6345

Now, I get an other kernel oops while connecting after entering the user name/password for the connection:
