This is really odd. I run 5.1 (actually CURRENT) on a T30 and have not
seen this for some time. You may need to go to CURRENT.

It may be an issue with some interaction. I will attach my
configuration files and dmesg for my T30.

Are you running ACPI or APM? I am running APM.

The only IRQ assignments shown in ps2 are:
Serial	 4
PCI	 11
IDE2	 15

Of course, other IRQs are in use, but they are not configurable. (psm,
IDE1, keyboard, clock, ...). The fxp0 uses the shared PCI IRQ.
