https://bugzilla.kernel.org/show_bug.cgi?id=197813 --- Comment #8 from biaoxiangye (biaoxiangye@xxxxxxx) --- hi, all We have several servers with the same cpu type, but just one of them occur this problem. So we guess it's a cpu defect, and after replace the cpu , the problem does not occur anymore. It seems like a cpu defect, but not 100% confirmation. -- You are receiving this mail because: You are watching the assignee of the bug.
