Can you tell me something about the hardware (processor model)?
You are not booting the system under VMWare by any chance?

As a matter of fact - I am compiling in a VMware Player (6.0.3
build-1895310) virtual machine, boot testing there, and then if everything
is OK, I transfer the monolithic kernel produced on 3 virtual machines that
run on EXSi and 2 actual servers. So along those lines - the failing
3.19-rc1 never saw actual hardware - it was all tested (and bisected) inside
a VM.

Thanks. VMWare having problems with my patch is a known issue. I've
already sent a patch working around that issue (VMWare has a bug
emulating the PAT MSR). You can either use that patch (attached for
your convenience) or use the "nopat" option.
