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 On Saturday 26 February 2005 01:50, Benjamin Herrenschmidt wrote: > On Fri, 2005-02-25 at 14:30 +0100, Mws wrote: > > hi, > > > > i also have problems with 2.6.11-rc5 and radeon: > > > > i am using a ATI Radeon X600 PciExpress. > > > > a) now the console framebuffer seems to bee working, thx benjamin :) > > b) when bootup seq ist completed and i want to start X (xorg-x11) with > > ati-drivers > > x is freezing - not your problem, but the console is not correctly > > restored :/ the only way > > out is to reset the machine :/ > > 2.6.11-rc3 was running fine in this case > > Hrm, the binary drivers ? oh well... some users had them freezing vs. > radeonfb before and not now.
