I've upgraded from Quantal to Raring on release day and have encountered this issue on 3 occasions since then (booted at least once a day, so it fails ~15% of the time). Rebooting after the error message is shown works fine for me. It never happened on Quantal or earlier.
My desktop PC is self-assembled as well, but my GPU is made by AMD, and I have fglrx installed. See attachment for ls{cpu,hw,pci} output. ** Attachment added: "ls" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1177086/+attachment/3676514/+files/ls -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1177086 Title: amd64: "Fixing recursive fault but reboot is needed!"
