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.
