I've just upgraded from an i386 to an x86_64.  It was an.... ordeal, but the 
kernel was the least of the worries.  Userland upgrades were a pain.

Using the same config as on i386 apart from the differences that a 'make 
oldconfig' threw up on the new architecture, I am now seeing some problems with 
the x86_64 that I was not seeing on i386 on this release.

Kernel messages like this when booting up:

They're not appearing all the time, so far mainly at boot time.

I've posted the full dmesg and config up at http://www.reub.net/files/kernel/

As this is the first release I've run on x86_64 I can't say how long this one 
has been showing up for ;)

Thanks,
Reuben
