yum FUTEX_WAIT and kernel not finding volgroups

[Adam Pribyl <pribyl lowlevel cz>]

During weekend I updated to current rawhide and I'm locked in 
"unupgradable" state.
Fist the new kernel (2.6.20-1.2947) install created broken initrd. This I 
fixed by making new one (I hope).

Then when I tried to use this kernel, it panics, 
because it can not find any volgroup00 on the disk.

Booting with older kernel 2.6.18-2798 I have is fine, but when I try to 
run yum or rpm it hangs. Stracing the process reveals it locks on 
FUTEX_WAIT (probably kernel related).

How can i get out of this state?

Thanks
