The crash below happens every time I boot 32-bit dom0 pvops on 64-bit
xen-unstable, but only on some machines.

Circumstantial evidence, to be confirmed, suggests that 32-bit PAE
pvops dom0 on 32-bit PAE Xen doesn't work either, and that the XCP
kernel works fine on this hardware.

Crash dump below is from:
 linux 2472a9ccf02b04a36300cf1d3515f3f14d40aa4b
 qemu  706bc8c588cbda284a9579cdb7e494ad5c9d6383
 xen   22267:00b92112b055

Massaging the oops file and feeding it and the dom0 kernel Symbols
file to ksymoops produces the output you find below.

Ian.
