    [Thinkpad T430s] System freezes randomly

    Hi all,

    On my lenovo thinkpad T430s, the latest ubuntu freezes randomly roughly once a day. I also tried other distros, including Arch, Fedora, Mint... none of them works perfectly --- they all freeze randomly.

    Right now, I didn't see anything useful from the log. When the system freezes, I can do nothing bot hard reboot --- Alt-Ctrl-F1 does not work, Ctrl-Alt-Backspace neither.

    The only (possible) useful piece of information from the log during boot is:

    Code:
    kernel: [    5.767141] [drm] MTRR allocation failed.  Graphics performance may suffer.
    Does anyone have similar problem with me?

    Regards,
    -Monnand

    P.S., I tried 3.4.11 kernel as well, it does not work for me.

    Hey there,

    I'm having the same problem with my T430s.

    I found this:
    http://askubuntu.com/questions/19005...-2101sl-freeze

    and this:
    http://partiallysanedeveloper.blogsp...ux-freeze.html

    I have just installed the 3.3.6 Kernel and now testing.

    Best Regards

    PS: just saw, you already tried kernel 3.4... Please update this post when you find a solution.

    1. I upgraded to kernel 3.4.11, and still have same problem
    2. I disabled the security chip from bios and still have same problem.

    Right now, I found this: http://partiallysanedeveloper.blogsp...ux-freeze.html

    it might be useful and I will try it later (and report my status after one week test.)

    Re: [Thinkpad T430s] System freezes randomly

    I wondered if the freezes and kernel panics are a Linux-only problem.

    I installed Windows 7 on my machine (plain Windows, with all updates and drivers, not the pre-installed windows version) and I experienced random blue screens with code 124.

    This is may be a hardware issue with the T430s:

    Thank you, m303.

    By following your link, I found more evidence about it:
    http://help.wfu.edu/thinkpads/t430s/status

    It seems like the problem of the hardware itself.

    I updated to kernel 3.6.2. It randomly panic (yes, kernel panic) with error messages (I will upload the error message soon.)

    Here is my solution: call lenovo tech support and tell them about the problem. They first said that the problem is because of the GNU/Linux itself and they are not responsible for it. I showed them some evidence I found online saying it is the hardware's problem. And fortunately, they said they will send me a box and let me send the laptop back and they will repair it.

    I am not sure if they can fix it. (It is possible that they start my computer, and decide not to fix it simply because of seeing a Linux on it.) I will keep reporting my status on this topic.

    As I mentioned, here is the screenshot on kernel panic.

    Quick update:

    Right now, my laptop is hold by lenovo for more than two weeks and still on "part hold" status. What's worse, their web-site always return an error with "StringIndexOutofBoundException". That means I cannot check status online and have to call them everyday, which also means I have to be put on hold on the telephone for *more than* 20 mins. In conclusion: Lenovo service sucks.

    That's really sad. My service experience was also not the best:

    Our IT people sent the notebook to Lenovo service (which is operated by Teleplan in Europe). They sent it back with a note not being able to reproduce the error.

    The system still kept freezing/bluescreening.

    Tomorrow someone from Lenovo (or Teleplan, don't know yet) will come in and have a look at it again, and hopefully replace the main board.

    m303,

    Here is what I did: I printed the web page from wfu ( http://help.wfu.edu/thinkpads/t430s/status ) and printed another sheet of paper saying: replace the motherboard!

    Fortunately, they decided to replace the mother board for me. But simply replacing the board takes two weeks and I am still waiting. I was told it may be back on next week, that is, 3 weeks in total. And they claim that they can fix it with 6 business days.

    EasyServ is the one that fixed my laptop.

    Re: [Thinkpad T430s] System freezes randomly

    Now I finally get my t430s back from lenovo. A summary on this problem:

    - Lenove replaced the motherboard. The problem of freezing is not because of software, it is because of the defective hardware.
    - I have been watching youtube for about an hour and there is not freeze until now. I will test more applications later
    - I sent my laptop on Oct 25 and get it back on Nov 15, which is more than 3 weeks. What's worse, their website always return HTTP 500 error making me impossible to check the repair status online. I have to call them everyday.

    In short, if you have same problem on your Thinkpad T430s, don't hesitate, it's not your fault, not GNU/Linux's fault, it's their defective hardware. Call lenovo, send your laptop back and let them to repair it. Remember: the repair may take longer than you expect. If you don't want to wait, you can return it for refund and buy a new one --- that will take less time.
