Comment (by lc):
I believe this is a timing issue with Zentel. I do not know what exactly
OpenWRT does shortly before triggering the actual restart. However we
played with sleep commands in /etc/rc.d/K99umount and found that if you
add a sleep of 5 seconds the reboot problem does not occur as often as
without. Unfortunately the issue does not go away completely, it just
seems to take more reboots before the device hangs. Can you reproduce this
change of behaviour?
{{{
procd: - reboot -
[ 163.230000] Removing MTD device #3 (rootfs_data) with use count 1
[ 163.250000] Restarting system.
}}}
Maybe a little more time (1 sec?) before the actual restart command is
issued could solve the problem. Currently it seems there is just 0,02
seconds between "Removing MTD device #3" and the actual restart. Do you
know where to increase this value or add a pause of 1 sec?
