If it matters, before I switched to ThinkPad T510, I had a Dell Inspiron
6400, also with Intel graphics. I was then hitting:
https://bugzilla.redhat.com/show_bug.cgi?id=537494
Which is:
http://bugzilla.kernel.org/show_bug.cgi?id=13811
Which is more or less the same bug. Essentially, pages get corrupted on
thaw after the hibernate/thaw cycle is repeated several times.
If you look at this comment of that Fedora bug:
https://bugzilla.redhat.com/show_bug.cgi?id=537494#c67
You will see that the problem has been fixed at some point.
But then the code regressed again. My guess is when the code was
rewritten in such a way that the patch that fixed kernel bug #13811 did
no apply any more.
