This is very likely related. Normally I'd say "Bad address" indicate user-space issue, but the only thing changed is the kernel version... It may be also that some kernel API have changed and the driver is using parts that weren't there before. Anyway, I've looked into 'intel' X driver sources and the version we currently have (2.99.917) is the latest one. On the other hand, there was over 800 commits since that release and some of them may be related. For example maybe this: https://bugs.freedesktop.org/show_bug.cgi?id=105886 This suggests you may want to try enabling or disabling composition, if i3wm supports it. > Duckduckgo-ing the error message yielded a few  Arch Linux bug > reports describing the same symptoms.
