-- forced to reboot here --

I only saw this bug once, while regtesting another bug (8934), with
2.6.22.5-cfs. 2.6.22 was used quite a lot before. 2.6.23-rc was booted several
times also, without the problem, but I cannot quarantee anything.

I still have the kernel image and System.map if you want.

Steps to reproduce:
Well, I got it only once, but it is in core components...
