Ok - so the apparent kernel memory leak appears to be associated with
RAID-1. I have RAID-0+1 configured.

To confirm another observation of mine, do you see lots of allocated
memory blocks for the controller?, e.g.

[EMAIL PROTECTED]:/home/imb> sysctl -a | grep ^ata_
ata_composit:    192,        0,  69703,    117,   406336
ata_request:     200,        0, 139406,     73,  2106449
                (size)  (max.)  (used)  (avail) (requests)

There appears to be a path through the ar driver which fails to free the
blocks recording the requests ..
