APM support with the Linux 2.1.108 kernel

Hi.

I have been using the 2.1.108 kernel without any patches on my laptop,
and have had a new problem with the APM support - one not present in the
2.0.34 kernel.

Unfortuantly, I could not tell you if this is new to the 2.1.x series,
as I have just gone over to using them. In any case, the problem is
that when APM is configured active, and the Power down on Halt option is
enabled, the laptop no longer powers off. The shutdown operation
completes successfully, and there are no other problems in this regard;
it simply does not power off any longer.

My question is: is this a bug in the APM support (and if so, I will
start hacking to fix the thang), or is it liable to be something I have
not thought of?

The laptop is a First International Computers 5500 model - AKA Toshiba
550xx, ViewMaster 550, and a few other names. The APM BIOS claims 1.1
compatibility, and had no problems functioning under the 2.0.32-34 APM
code, at least in these fields.

Additionally, the laptop has not does a successful suspend to disk under
Linux at any point, but I need to do more checking before I know that is
a bug - unless anyone can enlighten me...

Daniel
