I was able to reproduce this bug with vanilla 2.6.26.3 from kernel.org on my Eee 701 running Debian. I have the impression that it is related to http://bugzilla.kernel.org/show_bug.cgi?id=3584 and left comment #53 there. Sometimes the bug does *not* show with the vanilla kernel (but does with the Debian one), sometimes both show the bug. Blacklisting the 'battery' module seems to avoid it. Robert Epprecht
