A hypothesis was discussed in bug #1753012 that the root cause of this
bug was in the kernel, specifically in blk-core.c. The patch was finally
merged in kernel version 4.15.0-31-generic. I'm running on
4.15.0-32-generic but the bug is still happening:
1. Xorg starts to become unresponsive: it freezes, no input or output is
processed. It stays like that for not longer than 1 minute.
2. On resuming from suspend, Xorg coredumps
On Aug 16th, my Xorg started to become unresponsive, and on aug 17th it
coredumped when I resumed from suspend. I have the core file and the
crash report: where should I send them to?
