*** Bug 1549516 has been marked as a duplicate of this bug. *** I am getting a similar-looking backtrace, repeatedly. I wrote an analysis of the backtrace which is mostly me going "impossible!". "SIGBUS apparently at first instruction in XkbGeomRealloc(), when resuming from suspend" https://bugzilla.redhat.com/show_bug.cgi?id=1557682 Sadly it looks like xorg_backtrace() is also crashing in different places, this means there's ABRT reports that aren't getting merged correctly. I have followed "https://wiki.ubuntu.com/X/Backtracing#Untrap_signals" to disable xorg_backtrace(). Maybe the next time, a cleaner backtrace will help me analyze better. (DISCLAIMER. The manpage warns about consequences from this. Because X doesn't get to clean up if you do this. However with unprivileged X, _and_ me using XWayland rather than X accessing devices directly, I think it's fine. And if it's not, I should still get the backtrace saved to disk nicely and be able to reboot cleanly enough with sysrqs, because I have enabled sysrq). Google "Xwayland XkbGeomRealloc" is bringing this report up nice and prominently, so I'll mark mine as a duplicate. *** Bug 1557682 has been marked as a duplicate of this bug. *** Although, if you would like to click on [edit] next the title of this bug, and change it to refer XkbGeomRealloc() instead of _Uelf54_lookup_symbol(), that might also help highlight the *real* problem. I don't have permission to do that on this bug. Similar problem has been detected: This happened on resume from suspend. It does not always happen on resume from suspend. AFAIK this is the second time I've seen this backtrace. I have seen one other backtrace more frequently (and reported it). On this occasion I believe it affected my foreground GNOME session. It did not affect gdm, nor the GNOME session I had on a different tty (as a different user). reporter: libreport-2.9.3 backtrace_rating: 3 cmdline: /usr/bin/Xwayland :0 -rootless -terminate -core -listen 4 -listen 5 -displayfd 6 crash_function: _dl_fixup executable: /usr/bin/Xwayland journald_cursor: s=2dfd4bfd0b9c49e7bf8baeec3ec3ffc7;i=4e804b;b=23af529241b647dca1b9b199402b28f6;m=17420cf1d7;t=5681ae2205ed5;x=1e12814d65fea71b kernel: 4.15.10-300.fc27.x86_64 package: xorg-x11-server-Xwayland-1.19.6-5.fc27 reason: Xwayland killed by SIGBUS rootdir: / runlevel: N 5 type: CCpp uid: 1001 I found the elusive developer who's looking at this :).
