10.04, 10.10: fails to boot with kernel panic and getpwuid failed message

[Nick]

Happens inconsistently on boot up. Boots up successfully about 30% of the time. Also crashes about every 10 mins. when using internet. Error message: "GLib-WARNING **: getpwuid_r(): failed due to unknown user id (0)" is always returned.

Was running 9.04 with all updates previously and had no problems.

Hi Nick,

If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

Tested with vmlinuz-2.6.34-020634rc6-generic. Problem persists.

Similar problems here. I always get the message on Ubuntu 10.04. I only started noticing it about a month ago, thus my guess is that it wasn't there previously. Also I get the error message all the time, but everything seems to work fine.

On Ubuntu 10.10 (amd64) the error seems to be the reason why the installation does not start. I only see the "Ubuntu boot dots" running. After a while the error message is displayed, before the dots continue running.

I get about 1 in 4 failed boots in same way as originally reported.
Clean install of 10.10 64bit.
Not suffering any other problems.
Lenovo T61 Laptop.

[John Ainsworth (jaka-1)]

system crashes at random times with this same error message. i run 10.04 32bit.

I experience the same bug when trying to boot up 10.10 on a Dell Optiplex GX270. It is not intermittent, it happens ever time. I have not yet found a work-around.

I experience the same problem on a clean 10.10 64bit install (Lenovo T500).
Happens roughly on every other boot.
