Comment 25 for bug 531027

I'm having the same, or similar, problem under Beta 2 x64 Desktop using a USB drive to install. I ran the install in Expert Mode as the system was locking up at the boot screen with the Ubuntu logo and the orange/white dots it would freeze up and I would have to do hard reboot to get the system to respond. I am getting this error message on TTL 7:

(process: 399): GLib-WARNING **: getpwuid_r(): failed due to unknown user id (0)

and on TTL 1:

(initramfs) mount: mounting aufs on /root failed: Invalid argument aufs mount failed

 I have had problems ever since late in Alpha 3 prior to that I was able to run 10.04 without any serious issue but sometime during the Alpha 3 phase an update was released that caused my system to no longer boot. I reverted to 9.10. I tried to update to Beta 1 but the problem was still there (updated via the update manager not via a clean install).

This seems to be a serious and persistent problem that manifested itself late during the Alpha 3 phase. I hope someone with the know how takes a look at it before it's too late to be addressed.

I would be happy to do further testing I just need to be told what to do.
