ACPI Attach (acpi_ibm) stops mouse from working

[Tom Judge]

Hi,


I have recently setup an IBM/Lenovo T43 with RELENG_7 as of mid last 
week, however I have a problem with the acpi_ibm module.

If I add acpi_ibm_load="YES" to loader.conf I get the following message 
during boot:

psm0: unable to allocate IRQ

This is followed by a message stating that the acpi_ibm module has 
attached to IRQ 12.

If I remove this module from loader.conf and boot the system the mouse 
attaches and works as expected.  If I then kldload acpi_ibm the module 
attaches to acpi0.


Is there any way to make this work without loading the acpi module after 
boot?


Thanks

Tom
