Yep, with Fedora Core 8, and totally unchanged userspace, booting randconfigs of 
the latest -tip:master tree. This box has booted up over a million Linux kernels 
in the past 4+ years, so when it shows new types of sickness then in 99.9% of the 
cases it's something about the kernel.

The lockup went away after excluding x86/cpu. I'll try more testing as time 
permits.

Thanks,
