Hmm.  I just moved my sata_sil stuff out of the way and rebooted:

$ uptime; grep scsi_cmd_cache /proc/slabinfo
23:22:16 up 4 min,  1 user,  load average: 0.00, 0.03, 0.00
scsi_cmd_cache      1200   1200    384   10    1 : tunables   54   27 

8 : slabdata    120    120    $

Is this good or bad? I'm guessing it means it's still leaking. So it's
really starting to look like ata_piix is the problem. But we need someone
who has the leak to remove that and see if it helps. I can't, since my
drives are connected to it.

And developers:

Can anyone PLEASE take a look at this? We've got 4 confirmed reports of
it, and it's nothing to do with a tainted module. Take a look at this
slabtop output:

    OBJS ACTIVE  USE OBJ SIZE  SLABS OBJ/SLAB CACHE SIZE NAME
1230120 1230120 100%   0.38K 123012      10    492048K scsi_cmd_cache

I have a 492MB leak! And notice how objects never become unused - that
looks like the problem.
