I tried to find more information. It looks like the bugs has a similar reason as #393266 for xserver-xorg-video-savage, see also http://bugzilla.kernel.org/show_bug.cgi?id=7767. I installed debian's linux-image-2.6.25-2-686 from testing, and compiled vanilla 2.6.25.10 (+patches for tp-smapi, hdaps, linux-phc), but the error message still remains the same. Please let me know, if I can help. Sten
