No change - hangs the same way as before.

I recall it used to work with prior kernels and so I tried 2.6.31 from 
kernel.ubuntu.com/~kernel-ppa/

mainline/v2.6.31/ but that fails similarly. 

May be I could try 2.6.30 but from a bisect stand point thats not all that 
attractive even if we find it works..

Thanks,
