kernel BUG at include/linux/list.h:164!

[Konstantin Kletschke]

Hi Folks :)

I have a server at my hosting ISP, which got a new Kernel with
devmapper patches in it to use LVM2 with 2.6.x.

I test these patches at home, no error, but my Server crashes after a
couple of days, second time now.

2.6.6-rc2-mm1 with devmapper udm1 patch

Is this dump due to udma1 or not and the error is fixed now?
