[ltp] New glitch with 2.6 - no reboot with AC?

[linux-thinkpad@linux-thinkpad.org]

I've discovered a new glitch and I'm not sure when or how this appeared 
since I usually leave my R32 on.

It won't boot if I have AC plugged in.

Specifically, it won't begin LILO if I have AC plugged in, and I have to 
leave it unplugged for a while during boot or there's a kernel panic.

I've done a search for relevant terms, tried appending pci=noacpi, 
tinkered with the bios.  No luck.

The first few lines out of /var/log/messages are

Jul 22 20:32:52 debian kernel: ACPI: PM-Timer IO Port: 0x1008
Jul 22 20:32:52 debian kernel: Allocating PCI resources starting at 
40000000 (gap: 30000000:cf800000)

ro root=301 i8042.nomux=1
Jul 22 20:32:52 debian kernel: Local APIC disabled by BIOS -- you can 
enable it with "lapic"


if that helps.

Any advice?

Thanks!
