Re: Anyone else with hard lockup with PCI-express?
Yes, this problem has been around for a while if you're using the system under these circumstances:
PCI-Express or onboard 6150. Tested with 6200TC, 6600, 6150 all same result.
Playing any video file will either hard lock the whole system and/or the X windows system. If you use the VGA port instead of DVI, along with a VGA->Component transcoder like the 9a60, everything works fine without any changes to the xorg.conf.
