well.

One would suspect it's a filesystem issue, then.  A quick chec of 
fs/buffer.c shows that the panic is produced in remove_from_free_list(), and 
is caused when a block in the free list is not marked as free, which is 
probably a bad thing.  As for what can cause it, that's another issue.  It 
could be a broken physical filesystem, or it could be an SMP race condition, 
or it could just plain be a bug in the kernel.  The last two are really the 
same thing anyway, though.  So, firstly, check your filesystems, and make 
sure they're not broken.  Uh.  I dunno how you'd do that. ;)

but anyway, the point of this post was more that conjecture about where free 
lists are in the kernel is less useful than an old fashioned greppin'

;)
