Well.. That's a problem which only I can reproduce, and that only after
applying sched patches while performing strange acts upon small animals.
Plus I don't think we're close to fixing it.

More serious matters would be:

- The x86_64-goes-oom-due-to-bio-using-GFP_DMA bug. I'll send the patch
over today.

- The some-ati-timers-go-too-fast bug. I'll sndn that patch today as
well.

- Neil is sitting on a radi1 BIO leak fix which we need.

- It would be nice to get Martin MOKREJ
<mmokrejs@xxxxxxxxxxxxxxxxxxxxxx>'s full 16GB recognised again. Dave
Hansen is working on that.

- http://bugzilla.kernel.org/show_bug.cgi?id=6180 seems to be a recent
XFS regression.

- Matthew Grant <grantma@xxxxxxxxxxxxxxx>'s "rt_sigsuspend() does not
return EINTR on 2.6.16-rc2+" might be a new poll() bug, but that one's
hard and I suspect we'll need the extra testers which 2.6.16 will give to
be able to work out whether it's real and what the fix is.

- http://bugzilla.kernel.org/show_bug.cgi?id=6177 _looks_ like a serious
TCP regression, but that happened between 2.6.14 and 2.6.15 and that's
the only report I've seen.

Plus lots of other stuff, probably.
