currently my kernel/sys.c is at
f36854c: reboot: rigrate shutdown/reboot to boot cpu
which means I have your commit: a985941
I tried to checkout upstream kernel at commit: f36854c
even without your "ARM: imx: replace imx6q_restart() with mxc_restart()"
patch
I can reproduce system hang issue by "echo b > /proc/sysrq-trigger"
Thanks,
Jiada
