The second issue consists of what Hans described + an occassional hang on boot for resume from hibernation to disk. The second issue is still unfixed as of 4.16 + [PATCH v2] block: Change a rcu_read_{lock,unlock}_sched() pair into rcu_read_{lock,unlock}() vom Bart Van Asche, which Jens Axboe accepted¹. [1] https://patchwork.kernel.org/patch/10294287/ Currently compiling 4.16.1, but I do not expect a change, as there is nothing about blk-mq subsystem in the changelog as far as I saw. Will update [Bug 199077] [Possible REGRESSION, 4.16-rc4] Error updating SMART data during runtime and boot failures with blk_mq_terminate_expired in backtrace https://bugzilla.kernel.org/show_bug.cgi?id=199077 as well about the current state. The bug report contains a screenshot of one of the boot hangs. I had two more on Monday, but did not take the chance to make another photo. I will do so next time in case its convenient enough and compare whether it reveals anything more than my first photo. Thanks, -- Martin
