    Date
    hi benjamin

    now i had some spare time to do some investigation

    booting the 2.6.11-rc5 with radeonfb.default_dynclk=0 or with -1
    brings up a framebuffer console. everything is fine.
    starting xorg-x11 with Ati binary only drivers just brings up a black screen
    without a mouse cursor and freezes the hole machine. even network ect.
    is no more reachable from outside the machine. worst thing out of that
    a tail on the log files (on another machine) does immediately stop - also no
    output is written to syslog :/

    next scenario - test 2.6.11-rc5 with radeonfb.default_dynclock=0 and -1
    starting xorg-x11 with Xorg Radeon driver.
    a grey screen comes up - mouse cursor is visible and also able to move for
    5 - 8 seconds after screen display - then freezes the whole machine again.

    regards
    marcel
