https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D227352 Bug ID: 227352 Summary: 12-CURRENT (armv6) hangs on shutdown, often leaves file system not sync'd Product: Base System Version: CURRENT Hardware: arm OS: Any Status: New Severity: Affects Many People Priority: --- Component: arm Assignee: freebsd-arm@FreeBSD.org Reporter: bobf@mrp3.com using FreeBSD-12.0-CURRENT-arm-armv6-RPI-B-20180329-r331740.img with serial console enabled observed shutdown in serial console, and it hung at this point: Syncing disks, vnodes remaining... 0 timed out after powering off [obviously hung] and fsck'ing the SD card, the following problem was noted: CANNOT READ BLK: 7693632 In a previous shutdown attempt, it did something similar, and I corrected t= he problems with fsck by booting to single-user mode, mostly unreferenced file pointers. With the image in the state described above, I booted into single user, did 'fsck -y /' and had to repeat it because of a lot of unreferenced file pointers. I did 'sync' followed by another 'poweroff' [from the serial console] and observed the following: "Syncing disks, vnodes remaining... 0 4 timed out" booted single user again, did 'fsck -y /' twice (as required, since the fir= st time didn't correct all of the problems), then did 'sync' followed by 'poweroff' and got the following: "Syncing disks, vnodes remaining... 0 0 0 0 0 0 0 0 done" and then the system hung. booted single user again, ran fsck - no problems with the file system. uname output: FreeBSD pi1c 12.0-CURRENT FreeBSD 12.0-CURRENT #0 r331740: Thu Mar 29 23:19= :27 UTC 2018 root@releng3.nyi.freebsd.org:/usr/obj/usr/src/arm.armv6/sys/RP= I-B=20 arm dmesg output (first part) KDB: debugger backends: ddb KDB: current backend: ddb Copyright (c) 1992-2018 The FreeBSD Project.
