    Default 11.4 resume problems from s2ram Thinkpad R51

    Hi!

    I do have problems getting my R51 back from suspend. I have tried all hints from Suspend to RAM
    HCL:IBM Lenovo laptops - openSUSE and
    Problem with display remaining black after resume - ThinkWiki

    ... without luck. Disabling frame-buffer did not work but see below.

    Basically after resume my screen is messy. There are areas which show scatter others work well. Rest of the computer reacts "normal". Restart of X doesnt help, but reload radeon module does the trick, so I found the following:

    After init 3 and rmmod radeon he tells me:
    Code:
    linux-wjf9:~ # init 3
    linux-wjf9:~ # rmmod radeon
    ERROR: Module radeon is in use
    so I did :
    Code:
    linux-wjf9:~ # rmmod -f radeon; sleep1 ; modprobe radeon
    and voila - init 5 or gmd or X restart -> everything works fine until the next suspend.

    Summary:

    I think the problem is the radeon module: "reinit after the s2ram" and the frame-buffer on the console does prevent me - and maybe s2ram - to "refresh" properly. Correct?

    Ok so next I tried is to disable Frame Buffer, but that does not work at all.

    Kernel parameter vga=0 or vga=normal does not work as expected - First it works as expected text mode resolution is 80x25, but after some seconds the initramdisk does switch resolution of console again! I hate to say but it looks like OpenSuSe (again) thinks it is more clever than the user ...

    Since rmmod says "ERROR: Module radeon is in use" again, like before, I do think that somehow SuSe ignores my vga=0 ...

    Any ideas on this?

    some Info from the radeon module:

    Thumbs up [SOLVED] Re: 11.4 resume problems from s2ram Thinkpad R51

    Modesetting via the kernel (the problem I related to the Framebuffer stuff) can be disabled via another boot parameter: nomodeset.

    This disables vesa modes in vt1-6 but solves my problem with s2ram.

    Does anyone has a solution for both?

    cheers
