Oops

RouterOS General
1

I installed 5.0beta6 and am getting continuous oops issues requiring pulling the power supply to get running again. Unfortunately I can’t do a /system package downgrade after ftping the 4.11 packages as that also provokes an oops.

System is an RB433UAH with an R52

Typically I get something like this:

Any ideas?

Kernel oops is a case for support. Email support@mikrotik.com.

3

Done. Thanks.

4

Looking at the support link on the site, it seems I’m not eligible for support as I bought my routerboard from wifi-stock.com, not from mikrotik directly.

There harwdware / software, they are going to want to know what is up…


Drop support a message…

Ok, got a reply from support to do a netinstall of 4.11. Am stable again and going to leave the beta alone for a while.

Bit of a pain rolling back, as the export scripts from 5 aren’t all compatible with 4. It would be nice if the export script didn’t contain options that are the default. So if option foo is added to an interface and has default value bar, then foo=x is exported only if x != bar.
