[SOLVED] system restarts when trying to suspend

[john.ennew]

Hi,

I just installed a Hauppauge PCI digital TV tuner into my system. Now when I try and suspend to S3 it restarts. I did a complete reinstall of Ubuntu 8.04 to see if this would cure it but it still does it. I tried a vanilla install and then did a full system update to the latest kernel etc and both exhibit the problem.

How can I go about diagnosing the fault? I had a search round the internet but couldn't find anyone else with the same problems.

cat /var/log/pm-suspend.log

Many thanks,

I managed to stop the restart on suspend by disabling "Wake on PCI device" in the BIOS.

I was worried this would stop Wake on LAN as there isn't a separate option for this in my mainboards BIOS, however, this still appears to work.

Weird?!
