Kernel 2.6.2 and Thinkpad suspend

In the past I used kernel 2.4.20 quite successfully and during that time
the APM suspend worked perfectly. Now it does not. Closing the lid or
issuing the apm -S (or apm -s) command simply powers it down but the
little suspend light never comes on. When I press a ket to wake it back
up, it cmes back on but the fan does not. That is until I force a disk
access by doing a man or ls that is not cached.

I am aware of problems with APM in the 2.6.x kernels and I have tried
various patches found on the net. Some are i8042 related, some are kernel
related, some are apm related. None have worked. I get the feeling that
this problem is not being addressed but I know I must just not be loking
in the right place. Has anyone found a fix for what I think is a general
problem with APM? Are there any other Thinkpad users (A20M) that have a
resolution? Yes, I could go back to my earlier kernel but I don't want to
say uncle just yet.

I have a Thinkpad (A20M)2628-4TU with 256M RAM and am running Slackware
9.1 and kernel 2.6.2.

Thanks for your help.
Best,

Perhaps that's not the fan you're hearing but the harddisk spinning.

Even if the fan doesn't always run, is that such a problem? I personally
would think this a "feature", the fan not running 'till I needed it.

ACPI has come a _long_ way since the 2.4 series, why don't you give that
a go and see what happens?

What are Software Patents for?
To protect the small enterprise from bigger companies.

What do Software Patents do?
In its current form, they protect only companies with
big legal departments as they:
a.) Patent everything no matter how general
b.) Sue everybody. Even if the patent can be argued
invalid, small companies can ill-afford the
typical $500k cost of a law-suit (not to mention
years of harassment).

Don't let them take away your right to program
whatever you like. Make a stand on Software Patents
before its too late.
