Hi,
I can reliably reproduce a complete machine lockup when compiling
kernel sources with "make -j". After making some progress machine
stops responding to anything (including CapsLock/NumLock switching or
mouse moving) and after hard reboot nothing is left in kern.log or
syslog. Only attaching a serial console gives me the following clues
to what happens:

Interesting thing is that after such hang happens, I reboot the
machine and try to build again (this time with limited number of
threads) I get lots of "input/output errors" from make and messages
like the following in kern.log:
[ 186.518188] ecryptfs_decrypt_page: Error attempting to read lower
page; rc = [-4]
[ 186.522951] ecryptfs_decrypt_page: Error attempting to read lower
page; rc = [-4]
[ 186.522955] ecryptfs_readpage: Error decrypting page; rc = [-4]
[ 186.542690] Valid eCryptfs headers not found in file header region
or xattr region
[ 186.542694] Either the lower file is not in a valid eCryptfs
format, or the key could not be retrieved. Plaintext passthrough mode
is not enabled; returning -EIO
(As you can guess I'm building in my home directory which is ecryptfs.)
After that only doing "make distclean" allows me to compile kernel
again. And note that when I build with "make -j 10" everything works
fine (I have 2 CPUs with 4 cores each without hyper-threading).
So is it some bug or a known bad usage of ecryptfs?
Thank you,
Pavel

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:

what's the culprit?

How much memory does your system have? Doing so many fork()s could cause
a lot of resource conflict and memory pressure leading to heavy swapping
etc., which can ultimately hang your system, especially when your RAM
size is small. It is advisable to use make -j only on systems with lot
of RAM (> 3 or 4GB).

By the way "optimal" is supposed to be make -j <nr_cpus*2> isn't it?
IIRC, "maximal" refers to make -j

I'm sure I didn't make up that word "optimal" by myself. I took it
from some documentation or internet, although now I can't find where I
took it from. Wherever I look it says that -j is "unbounded" number of
threads.

I have 8GB of RAM. And it looks like you are at least partially right.
As I turn my swap off I don't see warnings about hung tasks anymore.
Lots of OOM killer messages pile up instead of that. But still even
when messages from OOM killer stop coming my machine remains
completely unusable. It doesn't react to key presses (NumLock and
CapsLock indicators don't work), display has no signal, and there's no
disk activity at all. Is it considered acceptable?

I was referring to the terms used by kernbench.
