Hi All, I am observing the following statements in the kernel log while running driver soak tests and monitoring MIPS and memory usage: [ 8350.824403] BUG: Bad page map in process python pte:000000c0 pmd:950a5067 [ 8351.457234] BUG: Bad page map in process python pte:3400000000000c0 pmd:950a5067 [ 8351.458469] BUG: Bad page map in process python pte:406486b3be206e97 pmd:950a5067 …. [ 8353.266053] BUG: Bad page map in process python pte:406486b3fb696e97 pmd:950a5067 [ 8353.305982] BUG: Bad page map in process python pte:000000c0 pmd:950a5067 [ 8355.738440] BUG: Bad rss-counter state mm:ffff880138fa7100 idx:1 val:259 [ 8374.905314] general protection fault: 0000 [#1] SMP In the kernel log, I observed that kernel reported 60 " BUG: Bad page map in process python ..." reports and 1 “BUG: Bad rss-counter state” and finally it crashed with “general protection fault”. I would like to know what does it mean by “BUG: Bad page map in process python ...” and how to identify the cause of it? To debug this, do I need to consider the “general protection fault” stack trace or the first “BUG: Bad page map in process …” stack trace? -- Thanks, Sekhar _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
