I’ve been happily using an EdgeRouter Lite (one of the first gen models) for just a touch over 3 years now. Everything worked amazingly well… Until one morning I woke up and my internet was down.
Everything looked normal, lights blinking, no warning lights, etc. After ruling out that my ISP was having issues, I decided to try and connect up my EdgeRouter via a browser. When I did this, I immediately knew there was an issue, I got a server 500 error. Not a DNS error, or some other HTTP error. So I power cycled the router, and same thing.
After digging out a console cable, I connected to the EdgeRouter and there is was… a Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(8,2) error.
