[Bug 904067] Re: Kernel panic - not syncing: VFS: unable to mount root fs on unknown block(0, 0)

  Thread Previous • Date Previous • • Thread Next 
Steve G., 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

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.

** Tags added: latest-bios-a10

** Changed in: linux (Ubuntu)
       Status: Confirmed => Incomplete

Title:
  Kernel panic - not syncing: VFS:  unable to mount root fs on unknown
  block(0,0)

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I upgraded to kernel 3.0.0-13 when this error occured first. I since
  booted Ubuntu from the 3.0.0-12 kernel, as this one still worked. I
  kept doing this until the recent kernel upgrade to 3.0.0-14, but I
  still get the same error message.

  I tried to find this message in a log, but it seems as if a) there is none or b) I'm too dumb to find it ;-). So I attached a picture with the error message.
