Okay, here is the diff between 2.6.34-git4 and 2.6.34-git5
It should be equivalent to make silentoldconfig as I made no
changes, just enter to accept defaults. The git4 boots and
git5 does not boot. (Both based off 2.6.34.1.config)
(and attached config-2.6.34-git4.gz, because .config was too
big for mail list last time.)

Can possibly duplicate problem if you have a
sata based PC from last few years.
Set CONFIG_ATA=m
and this becomes CONFIG_SATA_AHCI=m (cannot select=y)
Then 2.6.34.[01] (probably 2 also) will boot.
Make silentoldconfig with this .config and see
that 2.6.35 will not boot.
Thanks,
Don
