My setup: 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Tahiti XT [Radeon HD 7970] 04:00.0 VGA compatible controller: Advanced Micro Devices, Inc.

Server aborting (EE) (EE) This is on a gentoo box. I already open a bug at bugs.gentoo.org [1] where are additional information. Usually i'm using my hd7970 only for xen, but recently i wanted to try it out on gentoo too. However i couldn't get it to work yet. [1] <a href="https://bugs.gentoo.org/show_bug.cgi?id=484374">https://bugs.gentoo.org/show_bug.cgi?id=484374</a> I've also tried to create an bt. Below is what i got. For this backtrace i've rebuild mesa, xorg-server, glamor and xf86-video-ati with following settings: "-O1 -pipe -ggdb". I also wanted to build mesa with debug symbols, however it failed to build. The backtrace was done from another machine. (Is there a way todo it on the machine itself? Because when i try it starts X but never stops - and i couldn't do anything) I was testing via "gdb /usb/bin/X" This is what i got: #0 do_winsys_init (ws=0xf4fca0) at radeon_drm_winsys.c:212 #1 radeon_drm_winsys_create (fd=-1) at radeon_drm_winsys.c:617 #2 0x00007fe36429125c in create_screen (fd=<optimized out>) at target.c:11 #3 0x00007fe36453d998 in dri2_init_screen (sPriv=0x85b5b0) at dri2.c:877 #4 0x00007fe3606ab1ad in driCreateNewScreen (scrn=0, extensions=0x7fe3658a4b70 <loader_extensions>, driver_configs=0xf4f1b0, data=0xf4f110) at ../../../../src/mesa/drivers/dri/common/drisw_util.c:70 #5 0x00007fe3656777a7 in __glXDRIscreenProbe (pScreen=0xe78f50) at /var/tmp/portage/x11-base/xorg-server-1.14.4/work/xorg-server-1.14.4/glx/glxdriswrast.c:458 #6 0x00007fe365676d69 in GlxExtensionInit () at /var/tmp/portage/x11-base/xorg-server-1.14.4/work/xorg-server-1.14.4/glx/glxext.c:355 #7 0x00000000004a7efe in InitExtensions (argc=argc@entry=1, argv=argv@entry=0x7fffe91b9ee8) at /var/tmp/portage/x11-base/xorg-server-1.14.4/work/xorg-server-1.14.4/mi/miinitext.c:337 #8 0x00000000004281fa in main (argc=1, argv=0x7fffe91b9ee8, envp=<optimized out>) at /var/tmp/portage/x11-base/xorg-server-1.14.4/work/xorg-server-1.14.4/dix/main.c:208 A debugging session is active. Inferior 1 [process 3504] will be killed. Quit anyway? (y or n) I hope this can help somehow, if not i would need some assistance in how to create an proper backtrace for X :)</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
