You can run the stacktraces though addr2line (e.g. > addr2line -i -e /usr/lib/xorg/modules/drivers/intel_drv.so 0x638f7 > 0x68fbc 0x6a02b) Brief googling this didn't find anything I can grok. It's probably doable with minimal hand-holding, e.g. a URL explaining what tools need to be installed (gdb + ???) and how to use them. Debugging is something I do so infrequently I forget everything I managed to slog through from one session to the next. > but also compiling your own ddx with > --enable-debug=full would be very useful. Not doable. I tried programming in college over 4 decades ago. English remains as much language as I can cope with, and not even that much WRT OBS. OTOH, RPMs I can deal with. > A drm.debug=6 dmesg would tell you what is going on kernel side. Tell you maybe. :-) http://fm.no-ip.com/Tmp/Linux/Xorg/Igfx/panfault/ Fedora 21, kernel 4.0.4: dmsg-i915G-f21-k404crash.txt Tumbleweed, kernel 4.0.4: dmsg-i915G-os133-k404crash.txt Looks like maybe the crash occurred in the vicinity of [433.26] in F21, [111.57] in TW, but there's minimal sense I can make of dmesg generally. All this said, crash didn't happen in Rawhide, so maybe it's a kernel problem that has resolved itself post-4.0.4?
