Yes, that seems to have made it stop complaining about the IDE path.
Good, thanks for testing. It would be great if you left it running for
a couple of days like this to see whether there aren't any other issues
with the patch. I'll send it with a proper description to Dave soonish
since this is a real bug.
All I see from kmemleak now is:
Yep, not IDE-related. Adding linux-acpi.

...which is probably a separate, non-recurring leak.
Also, I'm sure you know IDE is deprecated, so what are the chances of
moving this box to libata? Also, can you send me your .config pls?
Yeah, I was going to get around to that eventually. :) Config (and
earlier kmemleak output) here: http://0x.ca/sim/ref/3.1-rc6-blue/
Ok, thanks.
I think I reported those already some time ago:
