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

[Bernd S. <ber...@we...>]

Hi Ari,

APM suspend/resume works on my R31 but every time /proc/apm is read, my mou=
se=20
cursor is jumping and the keyboard and mouse are making random input. Not=20
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=3D3723)

Cheers,
 Bernd
