Thanks for the confirmation.

Can you try to find the guilty commit through git bisecting?

IOW, please do:


# install git and cogito on your computer

# clone Linus' tree:
cg-clone \ 
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git

# start bisecting:
cd linux-2.6
git bisect start
git bisect bad b278240839e20fa9384ea430df463b367b90e04e
git bisect good dd77a4ee0f3981693d4229aa1d57cea9e526ff47

# start round
cp /path/to/.config .
make oldconfig
make
# install kernel, check whether it's good or bad, then:
git bisect [bad|good]
# start next round


After at about 8 reboots, you'll have found the guilty commit
("...  is first bad commit").


More information on git bisecting:
  man git-bisect


TIA
Adrian
