Some time ago I update my system to modular X (7.0.0 RC0 from Gentoo portage)
and Xorg starts to hang when I have dri enabled in my xorg.conf file (http://
I did some tests and this problem seems to be random. Sometimes xorg starts with
dri without any problems and sometimes it lockup the machine completly (Only
emergency reboot help here) I use Pegasos II machine with 1GB of ram (HighMem
enabled) and G4 1GHz CPU. My card is Radeon 9000 card with 128MB/128Bit/DVD/VIVO
(Take a look at http://www.tbs-software.com/morgoth/files/private/drm/lspci.txt)
I enable a drm debug and notice a nice fllod in syslog with:
[drm:drm_ioctl] pid=8363, cmd=0x20006444, nr=0x44, dev 0xe200, auth=1
[drm:drm_ioctl] ret = fffffff0
The complete log can be found at (http://www.tbs-software.com/morgoth/files/
private/drm/dri-syslog.txt) also I upload the XOrg.log from faulty startup
I test using slighy patched 2.6.13 and a vanilla kernel with identical result.
Also today I give a try to drm cvs snapshot ... same.
BTW I was able to found almost identical log (with the same problem) on net
(http://www.gg3.net/~chutz/gentoo/xorg/kernel.log.txt), but I have no ideas who
produce it ;(
