SOLVED: Kernel crash with vpnclient 4.8.02 and Linux 2.6.38+

Postby knobi » Mon Apr 18, 2011 5:18 pm

Hi,

when trying to run "vpnclient" under Linux 2.6.38, I get the following oops, after which the system is in a pretty broken state. Last working Kernel was 2.6.37.2. anyone seen this before? This is with a CentOS-5.6 userspace (64 bit) and Kernel 2.6.38.3.

Thanks
Martin

Seems you are right. At least I do not get the OOPS anymore. Thanks
