I have a similar problem (previously posted to this mailing list) with a 
Toshiba 8100 which locks up when atapci0 is called during the boot using 
recent kernels.

I can boot off an old 5.4-RELEASE kernel (May 2005) and can boot off the 
more recent kernels if I copy the old version of acpi.ko over the new 
version, which leads me to believe that it is changes in the ACPI code 
which are the source of the problem.

I've posted to the ACPI mailing list (I'm not aware of any responses).
