    X201 Laptop randomly freezing (completely)

    Hey all,

    I finally got ubuntu 10.04 installed on my new x201 lenovo thinkpad.

    I am experiencing complete locking of my system every so often. X freezes, I can't dump to a console (ctl+alt+f1-7) and i have sshd running and it does not respond once my system is locked up.

    I thought it was related to my USB or external monitor, but those things were not in use several times when it has locked.

    I don't see anything weird in my syslog or messages. My kernel doesn't panic (no caps lock flashes).

    I haven't experienced this in windows, so I think its in ubuntu. I will try using windows more, to see if I experience the problem there.

    I am a programmer so I am comfortable with code and such and want to dig in and see what is happening.

    Is there anyone who is experiencing a similar problem?
    Can anyone point me to some documentation on debugging these types of issues? More logs I should check? Settings I can turn on to get to the bottom of this?


    Any help or direction would be appreciated!

    Thanks,
    Jon

    Just a thought. If you have an internet connection on that computer, try doing an update. I had a couple of lock-ups on a clean install that went away after updating.

    I am fully up to date, thanks though.

    hi all,

    i do have the same problem here with my x201, running kubuntu 10.4

    I never experienced a freeze when running undocked (as far as i can remember), but experience a freezing machine once or twice a day when running docked and connected to an external monitor.

    ANY help is appreciated, as this really is annoying.

    My Kernel version: 2.6.32-24-generic

    thanks a lot,

    okay,

    thanks for your reply, here we go:

    Code:
    uname -r
    2.6.32-24-generic
    
    free -m
                 total       used       free     shared    buffers     cached
    Mem:          3761       2223       1537          0         73       1062
    -/+ buffers/cache:       1087       2674
    Swap:            0          0          0
    i have the feeling that sometimes it is related with Chromium (5.0.375.99 (51029) Ubuntu 10.04). At least when i close chromium i can -- in some cases -- prevent a total freeze...

    again, any help appreciated!
