Thinkpad and 2nd battery in Ultrabay

[Uwe Laverenz]

Hi,

I have problems with RELENG_6 with two different Thinkpads when I try to
use them with a 2nd battery. The first ThinkPad is a T41 which doesn't
boot completely, the last message from the kernel is this:

ad0: 57231MB <HTS726060M9AT00 MH4OA6BA> at ata0-master UDMA100

after that, the system hangs.

The second Thinkpad is a slightly newer R51 and it boots and runs fine
until the display is closed and opened again. This will freeze the
system immediately.

In both cases the problem only occurs when the second battery is
inserted.

Does anybody else experience these problems?

TIA,
Uwe
