Could you please post a dmesg from a 'boot -v' and a 'acpidmp -d -t'?
Note that the acpidump is pretty huge, so if you could put that on
a web page, or send this to me privately.

Also it would be helpfull to determine if the problem happens if SMP is
enabled.  Could you try an UP kernel for testing purpose only?
