Default Bug#517449: linux-image-2.6.26-2-vserver-amd64: still getting "task blocked for more than 120 seconds." kernel log messages

Happens to me yesterday with
linux-image-2.6.26-2-xen-amd64_2.6.26-19lenny2_amd64.deb in differents

Default Bug#517449: linux-image-2.6.26-2-vserver-amd64: still getting "task blocked for more than 120 seconds." kernel log messages

Hi all,

sorry if my message from yesterday was noise too, but I haven't
understood yet why those kernel log messages appear anyway. Somebody in
this bug report pointed out that those "INFO: task xy blocked for more
than 120 seconds." are only symptoms of the real problem. Could somebody
explain the actual problem to me please?

What I have learned from this and from other similar bug reports like
this yet is, that it has something to do with the load which is on the
machine. But that is not clear enough to me.

TIA and kind regards,

Timo

The problem is that a task has been in uninterruptible sleep (aka
IO-wait) for a long time, which probably means it is deadlocked due to a
lock imbalance or incorrect lock ordering. The warning should point to
which lock is involved, but that does not tell us where the buggy code
is.

As the load increases there is likely to be greater lock contention and
more chance of a bug in lock ordering actually causing deadlock.

(There were also some bugs in tickless (aka 'NOHZ') scheduling which
could also lead to this warning, but they have been fixed. Those bugs
mostly affected very idle machines.)
