Nothing new (was it meant to run remove_inode_queue() conditionaly inside
buffer_mapped() branch? ed did it that way). First is list of buffers at
time of destroy_inode, then process. If you want full oops trace, it is
available at http://platan.vc.cvut.cz/oops3.txt, but last part is always
iput. For now I'm back on test9, as I lost inetd.conf again :-( Someone
should shoot sendmail Debian maintainer... Running update-inetd at startup
is really bad idea, as fsck then usually removes both old and new inetd.conf,
so I'm back on inetd.conf from 25 Aug 1999 :-(((
Fields printed from buffer_head are b_next, b_blocknr, b_size, b_list,
b_count, b_state and b_inode. (oops now I see that I left
remove_inode_queue(bh) in printing loop (I copied it from
invalidate_inode_buffers()), but it should not hurt, I believe. Dirty buffers
should find its way to disk anyway, or not?)

BTW, running 'ksymoops < oops > oops.txt' is great source of errors below,
as it (probably) uses couple of unlinked temorary files...
