Re: TOI and kernel 3.7-3.8 resume problem

I'm having this same behavior, Milan.  I'm using 3.5 from the TOI PPA
for Ubuntu on a Lenovo Z-570.  Kernel 3.2 was working fine for me as
well. Have you tried to reproduce this in a virtual machine?  This
could make it easier for Nigel to reproduce the error (if I get the
chance, I'll try this as well).
