I saw 3 suspicious spins with i386/PAE kernel since I updated on May 15th/16th. I boot FreeBSD 12.0-RELEASES i386/PAE once per a day and shutdown each time and use BSD everyday. I start with console and decide whether I want to use X or not and if so, I run startx. In the past, startx didn't come up twice in 30 seconds or so and console wasn't responding. Both times, I wasn't able to monitor system and gave up - hard reset. I had another and similar symptom. This time, I had ran X for a while. I started moving about 2 of 100MB files from tmpfs to zfs, I started seeing system lagging and also high CPU usage by kernel and syncer by top. Ctrl-T on mv printed "runnable" and "running" a lot while "systat -vm" wasn't showing any IO activities. After a minute or longer, system came back to normal. I haven't run non-PAE kernel as much, once or twice since the SA. I don't know if this issue is PAE kernel only. I definitely hadn't seen before the SA.
