Re: Re: S1 and S3 on IBM Thinkpad don't work

[Bernd Schubert <bernd-schubert-S0/GAf8tV78@public.gmane.org>]

Hi Ari,

APM suspend/resume works on my R31 but every time /proc/apm is read, my mouse 
cursor is jumping and the keyboard and mouse are making random input. Not 
nice if one wants to work ...
Could you please try out my suspend script for S1?

rmmod uhci_hcd
sleep 10
echo 1 >/proc/acpi/sleep
sleep 10 #this is necessary, as it also freezes without
modprobe uhci_hcd

(see  http://bugme.osdl.org/show_bug.cgi?id=3723)

Cheers,
 Bernd
