Description Tobias Klausmann 2008-12-25 02:40:06 UTC 
Latest working kernel version: 2.6.27.10

Distribution: Gentoo
Hardware Environment: ES40, XP1000
Software Environment: gcc version 4.2.4 

Normal config using "zcat /proc/config.gz > .config && make oldconfig",
then "make all":

$ make all

Snippet is from -rc1 but .28 fails in the very same way (and all rc's did, too).

This has been discussed already on lkml:

If testing of the mentioned patch is needed, I'm all ears.
