ACPI Uninterruptable Sleep

If I type cat /proc/acpi/battery/BAT0/state more than once or twice after a boot, the process trying to access that file goes straight into "Uninterruptable sleep", or 'D' in ps.  I'm trying to figure out what is causing this, and I can't figure it out.

dmesg | grep ACPI

I really don't know what is up with this, and it is unfortunate that it happens so often, because it requires a hard reset.

I'm using -beyond in [extra] if you are wondering about kernel, and this is a Pentium M Centrino 1.7Ghz laptop.  Let me know if you need any more information.
