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

[Scott Moser]

Hi Michael,
  Thank you for your patch attached in comment 50 above.  A bot identified this as a fix for lucid, and subscribed ubuntu-sponsors which put this bug on the sponsorship queue at [1].

  You stated:
| This should resolve the problem for people getting "Task blocked" errors 
| without impacting the performance on ext4, it requires more testing, 
| interested parties can get the package from my ppa :

   Because of "it requires more testing", I've removed ubuntu-sponsors,
which means it will be dropped from that queue.  At some point in the
future, if you believe it has sufficient testing and would like to get
this SRU'd, please show evidence of that and re-subscribe ubuntu-
sponsors.

   Thanks again for your work.

  [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)
