Public bug reported:
I ran Feisty with no problems on my laptop (Panasonic Let's Note R6).
After installing Hardy, the machine would quickly overheat and lock up
whenever I did anything taxing the CPU's.
In an attempt to find the cause (and make the machine useable) I booted
with the last Feisty kernel (2.6.22) left from before the upgrade. The
machine works just fine with that change.
Pasting redacted, detailed machine information below (I would attach the
file instead, but that crashes Firefox 3 - I'm reporting that as another
bug):
