Thanks Geir for the pointers to the other bugs. The freeze happens
instantly.

I tried the following: started in recovery mode without X and the
freeze/hang happened even then. So it seemed like a kernel issue and
more like bug 319717.

I looked over the other bug and found a possible work-around - adding
'acpi_osi="!Windows 2006" to the kernel boot parameters. This seems to
have done the trick - after booting into the kernel with this parameter,
I don't see the freeze/hang issue anymore. However 319717 reports that
the issue was fixed in v2.6.31-rc1 which is the ubuntu 2.6.31-1.13
kernel. I am currently  running 2.6.31-17.

I have attached dmesg and kernel logs while booting with acpi_osi
parameter.

** Attachment added: "dmesg with acpi_osi set to '!Windows 2006'"
