kschmitt, this bug was reported a while ago and there hasn't been any
activity in it recently. We were wondering if this is still an issue? If
so, could you please test for this with the latest development release
of Ubuntu? ISO images are available from http://cdimage.ubuntu.com
/daily-live/current/ .

If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.11-rc5

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream
kernel-unable-to-test-upstream-VERSION-NUMBER

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

Title:
  System halts when entropy exhausted, continues when it receivews new
  entropy

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  The system halts when entropy is exhausted, then continues when it
  receives more entropy.

  This happens during boot, necessitating key-twiddling or mouse-
  jiggling in order to boot.

  Once the system is fully booted, if one pings it, pings work at first,
  then halt when the entropy is exhausted.  When new entropy is provided
  (mouse jiggle/key twiddle) they continue.

  I'm checking entropy by looking in
  /proc/sys/kernel/random/entropy_avail, and on this system it rarely
  peeks 200, and us usually wavering around 100.  That's really low, but
  it _should_not_matter_ if there is entropy or not for booting, normal
  operation, or basic TCP/IP usage.

  
  Note, I do not own this laptop, I was asked to fix it, and will return it to it's owner now, suggesting they install ubuntu 10.04 (which worked), or a different distro.  Hopefully there will be enough information in the bug report to track down why the system is using entropy all the time.
