Hi!

I have a simular problem, but it happends as soon I access the network.


The messages are folloing a "Unable to handle NULL pointer deference"
Kernel panic.

It seems that my problem is not hostap related cause I have the kernel
panic without the
hostap too, only without the SW TICK stuck messages every 2 secs.

I hope this can even help.
