Subject: Re: 2.6.35->2.6.36 regression, vanilla kernel panic, ppp or hrtimers crashing

I didn't try yet, but i enable more debugs and catch linked list corruption. 

Here is dumps from netconsole:

http://www.nuclearcat.com/ll2.txt		

I have another PC, also fails to run 2.6.36, but netconsole don't give 
anything.
Both PC's have strange issue with clock drifting away too much (on 2.6.35 and 
maybe even before).
