I've investigated this problem a little more. It turned our that
problem happens on ext4 filesystem too (initially I reported it on
ecryptfs and thought that it was somehow related to that). And it
looks like machine is not completely stalled, looks like it still
manages to do some work (repeated reports from hung task detector are
a little different). But I still can't understand what happens there.
I was able to catch some stack traces via the serial console (kernel
is 3.1-rc8 with minor changes). I've attached everything I caught. In
short: there's a lot of tasks that are repeatedly reported hung with
the following stack:

Among others there's khugepaged, compiz and unity processes apparently
waiting on disk read and even this:

(and then all CPUs stacks are inside cpuidle_idle_call)

So can somebody suggest how can I debug this problem further and
pinpoint the reason of such freeze? Or maybe someone has ideas on
what's the culprit?

Thank you,
Pavel
