Comment 10 for bug 973096

Same issue here, whith this error message in dmesg :
[ 5089.775520] do_general_protection: 63 callbacks suppressed
[ 5089.775525] Xorg[1213] general protection ip:7facdca1b6a9 sp:7fff77d5d2f0 error:0 in nvidia_drv.so[7facdc9ba000+6e0000]

I don't know if it is a coincidence but each time it appens, I had a flash video playing in firefox...
