I strongly suspect this is the same bug in upstream kernel v4.15, which causes this issue:
https://bugs.launchpad.net/ubuntu/+source/xorg- server/+bug/1760450/comments/6 I am basing this on the "signal 7" (SIGBUS), as this is relatively rare on x86 [1]. Also that it occurs inside xorg_backtrace() - this is also *supposed* to be relatively rare, because libunwind tries to use a clever trick to avoid reading wild pointers and dying with a segmentation fault [2]. [1] https://stackoverflow.com/questions/2089167/debugging-sigbus-on-x86-linux [2] https://lwn.net/Articles/502864/ I would also predict that the original fault was caused by fetching the first instruction of the function, but it looks like we don't have the symbol information for it.
