[heads up] - current post rc.6 update freezes on reboot

cmyster · 11-16-2017, 06:55 AM

There was a recent change to rc.6 in current a few days ago, and when I rebooted my server today for the first time since then, it froze after unmounting, forcing me to use the power button. Tested, happened again, can't debug ATM so I left it to run for now. Still no idea how but please note that it does happen.
(Full installation, x86_64, current, up-to-date, Dell OptiPlex 790)

I don't see how any of that could cause what you're seeing... :/

Found the issue. I had an NFS to a remote server and that server was acting funny. On switching to init6, there where processes stuck on the local mount, trying to unmount it and being stuck on it forever. lsof, cd, file, updatedb, du etc' would freeze on the local folder holding the mount and I needed to kill -9 them. When init6 was trying to kill all processes involved with that mount point, reboot would simply freeze with most FS already unmounted.
