With the latest kernel update in precise-proposed my Lenovo Edge 11 is no longer bootable and reliable runs into a kernel panic. I tried to capture a stacktrace with Alt-SysRq-1 but no message was written to kern.log. So I'm only able to provide a captured, digital image of the crash.
The new kernel is bootable into recovery console, but I don't know how to perform any diagnostics from where. Based on the kernel panic and due to the fact that i'm unable to activate networking in the recovery console I assume its a network related issue.
To report this bug, I'm running the previous kernel "Ubuntu 3.2.0-61.93-generic-pae 3.2.55" from precise-updates, which runs fine. I'll run apport-collect from this to provide my system details.
