"BUG at fs/jffs2/gc.c:337" with 2.6.22

[Uli Luckas]

Hi,
I have just upgraded my PXA based board's kernel from 2.6.21 to 2.6.22. Now 
shortly after booting into a brand new jffs2 rootfs I get the following BUG. 
A quick glance at the changeset did not reveal any relevant changes. Do you 
guys have any first guess, as to what could be happening? Does jffs2/2.6.22 
work for toher people?

Thanks for your time
Uli
