Hi,
I try to configure suspend to ram on my new Acer TravelMate 4651lci. I added the option acpi_sleep=s3_bios to my boot loader.

I can correctly suspend the laptop (echo -n mem > /sys/power/state). When I enter a key the laptop resumes also. Unfortunately the laptop freezes approximately 20 seconds later. The system doesn't react any more. I also do not get any error message on the screen.

I uploaded lspci, dmidecode, acpidmp and lspci -vv and interrupts to my website:
http://bram.be/lspci.txt
http://bram.be/dmidecode.txt
http://bram.be/acpidump.txt
http://bram.be/interrupts.txt

I tried it with several kernels (ubuntu 2.6.10 and the latest 2.6.12.3 (with and without acpi patch)). They all give the same result.

Any ideas on how to fix this?

Thanks,
Bram.
