Subject4.6.2 frequent crashes under memory + IO pressure
Hi,

a man's got to have a hobby, thus I'm running Android AOSP
builds on my home PC which has 4GB of RAM, 4GB swap.
Apparently it is not really adequate for the job but used to
work with a 4.4.10 kernel. Now I upgraded to 4.6.2
and it crashes usually within 30mins during compilation.
The crash is a hard hang, mouse doesn't move, no reaction
to keyboard, nothing in logs (systemd journal) after reboot.

Then I tried 4.5.7, it seems to be stable so far.

I'm using dm-crypt + lvm + ext4 (swap also in lvm).

Now I hooked up a laptop to the serial port and captured
some logs of the crash which seems to be repeating

[ 2240.842567] swapper/3: page allocation failure: order:0, mode:0x2200020(GFP_NOWAIT|__GFP_HIGH|__GFP_NOTRACK)
or
[ 2241.167986] SLUB: Unable to allocate memory on node -1, gfp=0x2080020(GFP_ATOMIC)

over and over. Based on the backtraces in the log I decided
to hot-unplug USB devices, and twice the kernel came
back to live, but on the 3rd crash it was dead for good.
Before I pressed the reset button I used SysRq-W. At the bottom
is a "BUG: workqueue lockup", it could be the result of
the log spew on serial console taking so long but it looks
like some IO is never completing.

Below I'm pasting some log snippets, let me know if you like
it so much you want more of it ;-/ The total log is about 1.7MB.


Thanks,
Johannes
