  1. #1

    Default laptop freeze

    my laptop Packard bell easynote sb85 with last bios update 4A03 . it works perfectly with opensuse 12.1 but when i install opensuse 12.3 or 13.1 , i have the same issue it freezes

    but if i click on mouse it starts working again my guess its power management problem with the new kernel . i didn't have this problem with other machines only on this laptop .

    so please help me ..

    thanks ..

    You mean that the machine "stops", like the clock gadget not updating every second, till you move
    the clock or click on something?

    I had a similar issue years ago. It was never solved. I found how to trick the machine to keep
    running, though. Please confirm the issue description and I'll give you ideas.

    Ok.

    Comment: you do not need to send me a PM with the contents of the reply on the thread. If my
    computer is working as it should, I notice the posts ;-)


    Ok, at least in my case any interrupt signal would keep awake the computer for some seconds, like a
    keypress, a mouse movement, a mouse click... but also something on the network (an incoming network
    packet generates an interrupt). So what I did was log into my router, which happens to be an
    embedded Linux machine, and send a ping every second to my computer, forever. This was enough to
    keep it awake. Of course, I had to do it every time I booted it... which was a nuisance. I was able
    to automate the procedure a bit, but not much.

    On the other hand, I also opened a Bugzilla at Novell, against the kernel. To prove the issue, I did
    a script that... let me see if I can remember. It was a one second delay loop, and on every
    iteration it checked how much time has passed since the previous iteration. If it was 2 seconds or
    more, it wrote the timestamp and time difference to a file.

    The result is a log file with entries every time the machine stopped processing, specifying for how
    long it stopped. I proved there could be delays of several minutes.

    Of course, at least in my case, the clock worked correctly: after every "freeze", it would still
    show the correct time to the second.


    I suppose I could dig out those scripts. I also did a pascal program to do it better. I must have it
    somewhere.

    In my case the issue ended because I bought another computer or with a kernel change, or both
    things. Maybe it was never solved, and I was the only one on the entire Earth suffering it, it
    seemed. Now there are two people... :-}

    But I would need to upgrade that machine again to see if my machine is still affected, which is very
    problematic to do.

    I'll try to find out the bug number. If I forget to tell you this data (bug data, scripts for
    checking, etc), just write a post here on this thread (ping) to remind me. I can not find out this
    data you need just now.

    My Bug number:

    https://bugzilla.novell.com/show_bug.cgi?id=350980

    I suggest you create a new one, with a reference to the old one, and an entry on the old to suggest
    look at the new one.

    The script I used is included on the bug, you could reuse it.

    thanks Robin for all your answers , i coudn't manage to find the right script to avoid this probelm

    but i could trick the machine physically .. now i have a usb mouse and i put something on my touch pad

    everything seems to work fine .. i think i just emulate a click event permanently . i know its not elegant but it works

    i will not give up to look for others solution and maybe the next kernel version will not have this probelm ..


    again thanks Robin for all your replies ..

    My script does not avoid the problem; it just creates a log that _proves_ there is a problem so that
    the developers look into it when you create the bugzilla. The issue is unbelievable, so you have to
    demonstrate you tell the truth.

    Well, that is very similar to what I told you I did. I configured my router to ping the machine
    every second.

    Next kernel WILL have the same problem, unless you start working and report the issue ASAP in bugzilla.

    Welcome.
