Re: Kernel Failure in previous boot

I just had another kernel panic on the 6.43rc11 version, so I would say the issue is probably not fixed. I'm probably going to downgrade to the most current bugfix version and see if that helps.

Re: Low ethernet speed using MK

This is very anoying. How can I get only 20 Mbps from Mikrotik/RB150?.
Well, the RB150 is probably the problem. I've never used a 150 before, but the CPU is fairly slow, and just running the bandwidth test eats up a lot of the CPU.
