Public bug reported:
After upgrading from Ubuntu 10.4 to 10.10, my machine hung during boot
process before boot splash appears. This happens with all kernels from
2.6.35 branch, but I can boot with the 2.6.32 kernel from 10.4.
After some minutes of a blank screen, there is a report of a hardware
error, see attachement for original.
Here's the last message I get:
-----

Some CPUs didn't answer in synchronization
This is not a software problem!
