I have this trouble for quite a while. Either in gnome or kde desktop, applications I open in desktop crash frequently. For instance, all the firefox browser windows close automatically without warning. Following are two examples.
Aug 21 11:05:49 localhost kernel: gnome-panel trap invalid operand rip:3b2b91707b rsp:7fffffd1d3e0 error:0
Aug 22 10:39:42 localhost kernel: python trap invalid operand rip:3b2b91707b rsp:7fffffd66fa0 error:0
This also happens with gnome-term and other programs on desktop. I thought it is gnome problem, but now using kde also has the same problem.
My machine is amd64 with abit av8 motherboard, installed with FC4. gdm version is 188.8.131.52. I recently updated the BIOS.
This trouble prevents me from working on the machine normally. Any help would be nice.
