during years I had several times “kernel failure” error on my routerboard. Most of them were rare, once a year.
Every time I had such issue I opened a ticket with Support and got answer: “upgrade your RouterOs”.
I can understand this approach but if I have a router that mount a “long”-term release and it doesn’t have configuration changed, I suppose it couold work for “long” time without upgrade.
Since new RouterOs version are released every month (or week) it’s likely that there’s always a newer version that one I’ve installed so I’m not sure if “upgrade” is a solution or a default answer.
Anyway when you faced with a kernel failure issue how did you do?
Did you upgrade RouterOS?
Did you use Netinstall?
Did you upgrade bootloader?
Or other?
The software is written by human beings and it is impossible to test a longer time than is available for the software.
If a problem occurs after months, it is obviously impossible to predict it sooner as it would take months before being tried for a long time.
Anyway when you faced with a kernel failure issue how did you do?
Send supout.rif to MikroTik Support.
Did you upgrade RouterOS?
No, because is already on long-term, I update the device after some month long-term is available, and no new bugs come out for what I use the device.
Did you use Netinstall?
No, only 1st time I receve from our distributor the device.
Did you upgrade bootloader?
Obviously, Yes, and also Factory RouterrBOOT when permitted/available
Or other?
I not understand what you mean with this question.
