I tried pin pointing what the problem was (see comment > 34) but I was not able to fix the problem. I saw Ben Gamari's bisection log (from 3.7->3.8), but I didn't realize that you had duplicated the bisection; I only saw your bump 4 months later, on 3.13. The OP reported this for a Dell Latitude E6400 with G98; are you running similar hardware? -- You are receiving this mail because: You are the assignee for the bug.
