Comment 44 for bug 561140

I just managed to boot with acpi=off. Though, if you can, booting the old kernel is a better option.

I really would like to know what more info I can give, since the bug was reported while running 2.6.32-19 and I assume not all the relevant stuff is in the report.

Last point; I think we have enough "me too" comments ;-) It seems, though it doesn't affect everyone, it is pretty wide spread. just hit the "This bug affects XX persons. Does this bug affect you?" link at the top.
