Subject: ACPI bay - 2.6.20-rc3-mm1 hangs on boot

Hi,

2.6.20-rc3-mm1 hangs on boot on my IBM T42p when compiled with ACPI_BAY=y. 
Below is the trace of two BUGs I get.

When compiled with ACPI_BAY=n, it boots fine.

The traces are hand-rewritten (no serial console on that machine), so I 
have omitted the code offsets in the stacktraces.

ACPI: ACPI Dock Station Driver
ACPI: \_SB_PCI0.IDE0.SCND.MSTR: found ejectable bay
ACPI: \_SB_PCI0.IDE0.SCND.MSTR: Adding notify handler
PM: Adding info for platform:bay.0
ACPI: Bay [\_SB_.PCI0.IDE0.SCND.MSTR] Added
