I experienced this problem also with 2.6.30-rc2-zen0 and don't know why no body
reacted or replied to that message:

http://thread.gmane.org/gmane.comp.file-systems.reiserfs.general/22225

it wasn't meant to be a troll attempt or something similar :\

anyways - it's  nice to have it in bugzilla now

I currently can't provide any further information from tests since the catalyst
graphics driver or xf86-video-ati prevent me from upgrading to 2.6.30-rc*
kernels (one doesn't support >2.6.28 - the other only produces black screen) and
working productively with this box on newer kernels ...

so unfortunately I can't start copying big amounts of files and watch dmesg /
debug output ... -> my graphics card would overheat ;(

Can you capture a sysrq+t when this is occuring? The lock is properly released,
but I have a hunch that another thread is waiting on ordered writeback.
