I think I have this problem with PAE as well. Machine is SMP
(hyperthreaded). PAE dom0 boots fine on CPU #0. PAE domU is bound to
CPU #1 by default and boots to the login prompt as well, but only with
NX disabled (and network disabled, but that's another story ...).
With NX-enabled domU boot I get this ...
(XEN) (file=traps.c, line=872) Non-priv domain attempted RDMSR(c0000080,00000000,20100000).
(XEN) (file=traps.c, line=864) Non-priv domain attempted WRMSR(c0000080,00000800,00000000).
... and the kernel crashes shortly later, I guess due to NX pte entry
without NX being enabled on CPU #1. It crashes right after the first
set_fixmap call which creates a pte entry with NX set.
