It was the kexec'ed kernel that oopsed - the first kernel had no issues.
It was kexec'ing from 2.6.34-rc4 to the same kernel.

After that I have tried to reboot via kexec to try to reproduce the
issue but it either hung completely or resulted in corrupted X and
non-moving cursor.
Kexec from Distro kernel to itself works just fine (Ubuntu 2.6.32-20) however.

I will start a bisect as soon as find time.
