(5) I sent the ubuntu-bug -w. It was saying that this is new install of ubuntu. That is not correc. The ubuntu is here about 7 months. (6) I see no files in /var/crash/ This person (see link) has very similar crashes so I would call it confirmation of a problem. I believe that drm (direct rendering manager) is sick. This link is a person showing same problems as I do implicating drm. http://askubuntu.com/questions/300147/how-can-i-troubleshoot-why-ubuntu-keeps-crashing-on-my-laptop/312343#312343 My story. I have DELL Inspiron 14z. Run Ubuntu 12.04. Gnome classic. I have installed VMWare and other things. Today I have uninstalled VMware tools, but I still see the errors, although so far in 6 hours the computer did not crash. That can change at any time. Have been running 12.04 on this hw from the time I got the computer for about 7 months. It was well behaved for most time. Few weeks ago (May 2013?) it started to crash once a week and then started to crash more. Some bad days crashes 3 times in one day. I suspected heat problem and replaced fan+sink and also updated BIOS but the computer still crashed after those changes. Ubuntu is updating itself every night. My story is similar to Peter on the link above. My computer worked fine, then few weeks ago started to crash with either complete shutdown on frozen desktop. At one time this was the last message in the log file before it crashed completely. I have two types of errors like Peter and both caused by drm (direct rendering manager). As you can see from the gap in time this was the last error before system died. <pre> Jun 23 18:50:54 mycomputer bluetoothd[904]: Endpoint unregistered: sender=:1.32 path=/MediaEndpoint/A2DPSink Jun 23 18:51:42 mycomputer kernel: [ 111.363166] [drm:gen6_sanitize_pm] *ERROR* Power management discrepancy: GEN6_RP_INTERRUPT_LIMITS expected 17070000, was 17000000 //see time gap before reboot Jun 23 18:55:31 mycomputer kernel: [ 340.123935] CPU2: Package power limit notification (total events = 229) </pre> But note that on that day I saw this error 6 times but the system crashed only 3 times. I also like Peter have another error: <pre> Jun 23 19:21:55 mycomputer kernel: [ 36.323966] [drm] Driver supports precise vblank timestamp query. Jun 23 19:21:55 mycomputer kernel: [ 36.324114] [drm:intel_dsm_platform_mux_info] *ERROR* MUX INFO call failed </pre> Both of these errors are caused by drm (direct rendering manager). The sanitize_pm seems to be more correlated with crashes. It occurred 6 times in one day. There were 3 crashes, 2 were dead computer, 1 was dead desktop). One of the 6 errors was the last log message before computer died. Thank you for listening. If you need more info pls ask.
