in Q/omap4 we enforced vm.min_free_kbytes=32K at kernel level, while in
P/omap4 we had the installer tune that value for us (and put a file in
/etc/sysctl.d after the installation): i've been compiling the last two
days with no problem on my panda so far, closing here.

I'm all for kernel fixes, if we can sort out a decent testing strategy
to make sure it (a) fixes the bug, and (b) doesn't cause a regression.
Would make our buildds pretty happy if we backported it to precise too.

Bugs,
since we now dropped jasper-initramfs from quantal on we dont have a
place to put the sysctl.d hack anymore which causes this bug to show up
again in quantal images but along that we got a hint to replace
GFP_ATOMIC by GFP_KERNEL in the relevant kmallocs which worked for the
rt2x00 wifi driver in
the same issue is seen on omap3 beagleboard images, so also opening
against the linux package.

bug #992786 implies that this needs to be higher for sane performance.
Testing here with 32768 works well.
I'm not sure having this as an installer hack is sane, though I'm trying
to sort out where it's better put. procps owns that directory, but
having procps have subarch specific magic is a
With 12288, I still see both page allocation failures and eth0: kevent
