Besides the two reports of freezes on bugzilla.kernel.org (9511, 6307), the following two bug reports on bugzilla.redhat.com are almost certainly due to the same cause (imo, of course): 245834, 227234.

Ubuntu launchpad bug 158849 also seems to report the same problem, for an HP dv6258se 64-bit machine.

Also this one: http://www.mail-archive.com/[email protected]/msg10321.html

If you want to collect dmidecode data from these folks, perhaps we might get a wider sense of what categories of machines are affected. They all seem to be recemt HP and Compaq AMD64 laptops, probably all Quanta motherboards.
