Hello,

I am experiencing weird system hangs. Once about 2-5 weeks system freezes
and stops accepting remote connections, so it is no longer possible to
connect to most important services: smtp (postfix), www (squid) or even
ssh. Such connection is accepted but then it hangs.

What is strange, that previously established ssh session is usable. It is
possible to work on such system until you do something stupid like "less
/var/log/all.log". Using strace I found that process blocks on:

Is this a regression? If so, what's the most recent kernel that didn't show
the problem?

The symptoms could be consistent with some place doing a
balance_dirty_pages while holding a lock that is required for IO, but I can't
see a smoking gun (you've got contention on i_mutex, but that should be
OK).

OK. It did it again :(, so I send additional debug information. Today I discovered that "echo i > /proc/sysrq-trigger" makes my system being usable.

Can you see if there is any memory under writeback that isn't being
completed (sysrq+M),

also a list the locks held after the hang might be
helpful (compile in lockdep and sysrq+D)

Is anything currently running? (sysrq+P

Empty.

and even a full sysrq+T task list
could be useful).
