Hello,

This is what I could get.

 <0>Kernel Panic:  Fatal exception in interrupt
In interrupt handler - not synching
==========================

Getting this in your logs looks rather - hmm - amusing, to say the least:

Anyway, I also attach my .config file.

I also have vm.min_free_kbytes = 1024 in /etc/sysctl.conf, which is 
already 4 times the default value for my 64MB ram.

This info was gathered on a clean boot - obviously.
