latest -git: BUG: unable to handle kernel paging request (numaq_tsc_disable)

[Vegard Nossum]

Hi,

This actually hardlocked my machine and I had to add an extra patch to
get any output at all. Base version is latest git, commit
1fca25427482387689fa27594c992a961d98768f.

Excerpt from config:

CONFIG_X86_NUMAQ=y
CONFIG_X86_SUMMIT_NUMA=y
CONFIG_NUMA=y
# CONFIG_ACPI_NUMA is not set

My machine is of course no NUMA, just a plain P4 with HT. Crash
happens when I try to online CPU1.

Booting processor 1/1 ip 6000

Config is at http://master.kernel.org/~vegard/bugs/20080820-numaq/
already, but vmlinux is 122M so I guess it's better to ask if I should
provide line numbers.

the programmer was not looking is intellectually dishonest as it
disguises that the error is the programmer's own creation."
