Subject: reboot fails on at91sam9g20 with kernel 4.x
Date: Wed, 23 Nov 2016 17:13:05 +0100 [thread overview]
Message-ID: <2093786.uQmBVvCouf@ada> (raw)
Hei hei,
while upgrading a at91sam9g20 based board to a recent kernel I stumbled
over a problem I can not solve by myself. We have a board which is more
or less a stripped down version of the at91sam9g20ek. The kernels I was
trying lately with a custom DT were 3.14.79, 3.18.44 (didn't work),
4.4.32, 4.8.6 and 4.9-rc6+. The rootfs is built with
OSELAS.Toolchain-2014.12.2, ptxdist 2016.11.0, gcc 4.9.2, glibc 2.20,
busybox v1.24.2 and it's on a UBIFS on NAND flash.
The following happens if I try to reboot a 4.x kernel from console:
The system is going down NOW!
Sent SIGTERM to all processes
macb fffc4000.ethernet eth0: link down
Requesting system reboot
reboot: Restarting system
Reboot failed -- System halted
The last message obviously comes from arch/arm/kernel/reboot.c and
something fails. ;-)
Searching the web I found someone having a similar problem here:

Reboot works with 3.x kernels (if they run at all). I'll try a 4.1
tomorrow, but I would be happy if someone could assist me in debugging
this.
