On Linux brodtgaard 2.6.7 #1 Thu Jul 8 00:32:54 CEST 2004 i686 GNU/Linux
I got the following when running badblocks on /dev/hdb4, hdb is a Maxtor IDE disk which does have bad blocks.
After this the badblocks process hanged in D-state in lock_page() with load 1.0
Jul  8 04:55:52 brodtgaard vmunix: kernel BUG at 
drivers/block/as-iosched.c:312!

Looks pretty bad, the hash list is corrupted. Is it easily reproducable? If so, can you try with this applied and see if it catches anything?
