I've got a HP laptop (a Pavilion ZV5240CA) running a 2.6.12.6 kernel.
This as a pentium 4 hyperthreaded chip.
cat /sys/power/state gives: standby mem disk
echo mem > /sys/power/state as root does nothing. Nothing appears in
the logs either.
Any suggestions?

Try any reasonably new kernel, with cpu hotplug enabled.

Thanks, Sharp!
Thanks for the reply. Unfortunately that isn't an option for me (unless
2.6.12.6 supports it, which I don't think it does); the 2.6.1[34] series
are badly broken on this box; disk response is x100 slower. The problem
seems to be in the acpi subsystem, but I'm not sure. It's been reported
on this list, on the linux-ide list and most recently at
bugzilla.kernel.org [Bug 5594]; so far nobody has come up with a
workable fix or diagnosis (there was a suggestion about the default IRQ
used for ide, but I couldn't find where that was set in the kernel [I've
never hacked the kernel]).

You have to debug the irq issue first, then. You can try searching for
patch that breaks it or something like that.
