Ths is a re-send, haven't received any response, haven't seen any
newer snapshots. Attempted to build today with 2.5.47 bk tree, exact
same error. 
When new code?

Sorry for delay.

We hope to produce new snapshot to-morrow.

For now just comment out 

inode->i_version = ++event;

in line 265 of fs/reiser4/plugin/item/static_stat.c---you are just
compiling with newer version of core kernel than one snapshot was made for.

Code now builds, module will not install:

 modprobe reiser4
/lib/modules/2.5.47-rfs/kernel/fs/reiser4/reiser4.o: unresolved symbol 
balance_dirty_pages
/lib/modules/2.5.47-rfs/kernel/fs/reiser4/reiser4.o: unresolved symbol 
page_states__per_cpu
/lib/modules/2.5.47-rfs/kernel/fs/reiser4/reiser4.o: insmod 
/lib/modules/2.5.47-rfs/kernel/fs/reiser4/reiser4.o failed
/lib/modules/2.5.47-rfs/kernel/fs/reiser4/reiser4.o: insmod reiser4 failed
-------------
Will be re-trying on a different machine.
Will try to build reiser4 into the kernel this time.

Hmm. This is strange. balance_dirty_pages() is marked
EXPORT_SYMBOL_GPL() in mm/page-writeback.c.

Yes, this is known bug in the handling of exports of per-cpu data. Try
