We have performed several software upgrades on our RB1100AH, after each system... restart, it does not come back online, and has required a power cycle to bring it back. We did the most recent installation of ROS5.5 today, and had a console port plugged in to watch if there was any indication of a problem.

Again, after system... restart, the RB1100AH did not come back online, with "Restarting system" being the last message on the console. After a power-cycle, the router comes back with the new ROS just fine.

Here is the output of the console during the upgrade...

> system reboot
Reboot, yes? [y/N]:

Any suggestions?

WE have seen this on a number of boards in the newer v5 hardware. I would let it reboot and send a supout to MT.

it's also happen on my rb1200
but i think it isn't a really big problem...
after upgraded, my RB just work normally, even each reboot

Leo, you only have one local board is it?

Imagine you have to upgrade 50 customers at 300 km of you and you have to call them to power cycle the main firewall.. xDDD

They will say: WTF¿?!

This happened to me a couple times on 2 rb1200's. I think it happened when I upgraded both of them. One time it happened when i reset the config with the no-defaults option too.

Just happened to me on RB1200 upgrading from 5.2 to 5.5. Did this remotely so I had the remote hands guys unplug the rb1200 and plug it back in and it still would not come up. Finally I had my tech go down to the datacenter and unlplug the power and wait for almost a minute before plugging the power back in. After that it came up on version 5.5. Did some more testing and found if you put the power plug back in too quickly after pulling it the RB1200 will not boot up. Strange stuff.

please make a supout.rif file and send to our support email so we can find the problem

The same thing is happening here, on an RB600 that I dusted off and started testing. Once I upgraded it to 5.5 using netinstall, it started giving this same message during every boot:

Press any key within 2 seconds to enter setup..
loading kernel from nand... OK
setting up elf image... OK
jumping to kernel code
Starting...
mount: Mounting ubi0:Kernel on /boot failed: No such device

Upgrading to the latest firmware made no difference. supout.rif on the way to support@mikrotik.com...
