	hy,

I hope I can give with this little document a little overview about the pro=
blem
=66rom 2.6 with some of the new IBM Thinkpad laptops. My english is not the=
 best
but I hope that it will help the people to see what's going wrong.

First: cpufreqd

If I boot with AC connectet the cpu will be detected with 1499 Mhz max.
If I boot from akku only 599 Mhz max will be detected.=20

Second: ACPI

complete broken some fixes you can find in :
http://bugme.osdl.org/show_bug.cgi?id=3D1038

But It fixes not al error's and problems.

Third : APM and suspend

apm work fine but there are many problems with suspend.=20

Usb is not suspend save. You must stop hotplug, rmmod all modules for
Suspending

XFree is not suspend save. You must change to an text base console stoping X
and then suspend

If I activate the two synaptic devices the thinkpad has after resume the
synaptics is broken. I have disabled the touchpad in bios and use only the
litte red pad in teh keyboard suspend and resume works fine.

On windows I can sit in the garden from my parents surfing via wlan the akku
keeps the laptop running nearly 6 hours. On linux the max time I reached wa=
s 4
hours with the cpu @ 74 Mhz.

There are many debug messages on suspending und resume. Do we need them all?

The problems are all with 2.6.0-tes8-bk1.

Many people found the same errors on the laptop's not only on Thinkpads. Th=
e X
problem was found on ati radeon at 128 and the intel graphic boards so that=
 it
seems that it is not an bug in one driver.

Is there some work in progess? Are some patches outside I can test?
