http://www.zip.com.au/~akpm/linux/patches/2.5/2.5.70-mm1.gz

  Will appear soon at

. A number of fixes against the ext3 work which Alex and I have been doing.
  This code is stable now.  I'm using it on my main SMP desktop machine.

  These are major changes to a major filesystem.  I would ask that
  interested parties now subject these patches to stresstesting and to
  performance testing.  The performance gains on SMP will be significant.

. I dropped the kexec patches.  Mainly because the sheer extent of the -mm
  diffs is getting in the way of other work, and the kexec patches
  significantly altered the arch/i386 code where other things are happening.

-mm has modules changes.  Is CONFIG_DEBUG_PAGEALLOC enabled?

No.  I have been running 69-mm8 for several days without problems.   It 
would seem to be an initialization problem, 70-mm1 has now been 3 hours
here.

I have run 50 fsx tests overnight on a 8 way PIII SMP box.  Each fsx 
test reads/writes on it's own ext3 filesystem.  The 50 filesystems  
spread over 10 disks.

Some kernel oops happened during the test. One fsx test becomes 
unresponsive. The kernek did not hang.  Here are the three kinds of 
oops.  The first and the last kind happened only once, the second kind 
of oops happened several times.

Thanks for doing that.  I've found a couple of bugs which might explain two
of these.  I'll try the many-fsx test too.  -mm2 should be better.

OK, a 10x improvement isn't too bad.  I'm hoping the gap between ext2 and
ext3 is mainly idle time and not spinning-on-locks time.

Bah.  In inode_setattr(), move the mark_inode_dirty() outside
lock_kernel().

I think that's ext3 busily kicking the living crap out of semaphores ;-)

Actually we can just ditch it.

But I deleted them all!.  Well.  There is one semaphore left in ext3/jbd,
and that is for serialisation around the oh-shit-we're-out-of-space
checkpointing code.  I shall go on a hat diet if that is being a problem.

hmm, very odd.

Well, that just seems to make the box hang in SDET (actually, moving it
outside lock_kernel makes it hang in a similar way). Not sure it's 
*caused* by this ... it might just change timing enough to trigger it.

ALT+sysrq info attatched, compressed, cause there's so many stinking
processes running ;-)

Yes, sorry.  Looks like you hit the filemap.c screwup.  The below should
fix it.

OK, seems to work now, but it's still no faster:

(last one has both your patches in).

I had the sem tracing one in there too, but got no output. I might have
another look at that later on ...
