Yes

Yes !

Just to be 100% clear, the hang I was seeing at the second suspend is this one:

Subject    : second suspend to disk in a row results in an oops  (libata?)
References : http://lkml.org/lkml/2007/3/17/43
Submitter  : Thomas Meyer <thomas@m3y3r.de>
Status     : unknown

I'm not sure it was associated with the MSI issue yet.

Thanks a lot,
Fred
