I'm very sure that it happens to every 15.04 system running continuously
24/7. BUT it seem to be very much related to the java-stuff involved in
running Jenkins or a TeamCity agent (as with the actual affected
system).
I have not upgraded the BIOS yet - and I do not think that it could
affect it.
On one of the machine suffering from this I run jenkins. Shutting down
jenkins immediately gets kswapd back to normal. Starting jenkins again
makes kswapd spin again. But a reboot mitigates the problem for several
days.
I'll keep investigating this.

For some reason the system still used kernel 3.13 after the upgrade - on which
it failed. Upgrading to 3.19 did not change anything.
I have difficulties believing that and userspace sutff could cause it, but
maybe
the systemd-stuff could affect it anyhow.

I don't know what changes has gone into the trusty 3.11 or 3.12 kernel.
but if I should bisect based in "threadirqs" I would make 3.12 as good
and 3.13 as bad based on my comment from yesterday :
v3.12-trusty/ seems to work for me. So to me it seem to have broken between
3.12 and 3.13. For sure
v3.11.10.4-saucy + "threadirqs" works OK, but the 3.11-lowlatency that
trusty had back in January did not. This issue is getting me down as far
as managing all the different version. :)

Apparently CONFIG_IRQ_FORCED_THREADING_DEFAULT is not an upstream config
flag.
The resulting param force_irqthreads is not set no true unless
"threadirqs" are on the kernel commandline.
In the problematic kernel it is set to true by default - something that
will never happen on a vanilla kernel.
We seem some more skilled people than me on this. It seem like the error
start at one thing, but then progresses and pull the IO subsystem down
(the IO-error that I also get).
