[Bug 624877] Re: INFO: task dpkg:23317 blocked for more than 120 seconds.

[Launchpad Bug Tracker]

This bug was fixed in the package dpkg - 1.15.5.6ubuntu4.6

---------------
dpkg (1.15.5.6ubuntu4.6) lucid-proposed; urgency=low

  * Cherry-pick fixes for sync() behaviour in dpkg (LP: #624877):
    - Disable by default usage of synchronous sync(2), as it causes undesired
      I/O on unrelated file systems. Closes: #588339, #595927, #600075
    - On Linux use sync_file_range() to initiate asynchronous writeback
      of just unpacked files. Suggested by Ted Ts'o <tytso at mit.edu>.
      Thanks to Jonathan Nieder <jrnieder at gmail.com>. Closes: #605009

  [Original Report]
  I try´d today to update my system with "aptitude update && aptitude dist-upgrade -y"

  Every time its stick on

  Preparing to replace language-pack-en-base 1:10.04+20100422 (using .../language-pack-en-base_1%3a10.04+20100714_all.deb) ...
  Unpacking replacement language-pack-en-base ...

  when I try to kill the task with "kill -9 9440" I have still no
  success.

          ├─screen(22470)─┬─bash(22471)───aptitude(9407)─┬─dpkg(9440)
          │               │                              └─{aptitude}(9408)
          │               └─bash(22500)───pstree(9460)

  only when I kill 9408 I can interupt the command.

  My dmesg ist full of curious messages (see file I attach)
