There's at least one critical bug in 2.6.38 which I can confirm on all
devices I tested (x86 and x86_64 arch). IMO it makes 2.6.38 unusable for
the time being.

The mainboard chipsets and CPU become very hot. On one device I tested
it almost fried the WiFi chipset.
In my opinion - I can't prove it by hard facts - 2.6.38 also has some
serious performance regressions. Web browsing becomes almost impossible
on older devices, as soon as more than 3 or 4 tabs are open. Current
kernel looks more like work in progress to me than a stable release.
