Was about to send this same report.

The thing continues servicing files it seems, but after some quite
good delay.

This happens after massive amount of writes. 2.6.29.4 does the
same thing. Here it is, for comparison:

No idea why it is tainted - probably the r8169 lockups.
The same page allocation failure happens on a freshly
booted kernel too (untainted) - after about half a
hour of constant writing to the same file (i were tarring
a large filesystem to the remote server), on a 2gb machine
which does nothing else.

Thanks.
