Anybody else seeing frequent kernel panics in refile_inode (called from 
__remove_inode_page, called from shrink_cache) on 2.4.22-1.2188.nptlsmp?

I've filed a bug report in Bugzilla, if you experience similar panics 
you could help tracking it down:

There's also a bug with exactly the same symptoms which the Redhat guys 
claim to have fixed in 2.4.22-1.2190 test kernel update, but in my case 
the panice still occur.

The text of panic usually looks like this (the top of call trace look 
always teh same, down to the function try_to_free_pages_zone):
