Getting some trouble using the kowpow algorithm on a RX VEGA 64.

On occasion of variance, the [kernel 2 compiled for gfx901] results in corrupt shares afterwards untill it does a new kernel compile.

It's seemingly random at the moment and I've tried voltage, clock adjustment on the gpu/vmem to help, keeps happening on stock or changed variables.


Code:
[13:19:35] kernel 2 compiled for gfx901

Any knowledge on why it does a bad [kernel 2 compiled]?

Hi, unfortunately this is known issue for Vega gpu's(something to do with broken OpenCL compiler in drivers, and this need some tricks in code to make drivers provide correct binary). So far only kernel 1 works fine, but with lower hashrate. And this issue in my TODO list.

@andrucrypt, Hello. Please advise how to autostart the miner on ubuntu 18 boot? Tried creating a new service but the miner does not start unlike other miners. All I have is a miner start script in my task manager though mining will not start. Manual start is fine.
Well, I'm not a Linux guy, sorry, can't help here. But I believe it should be the same way as running any other app at start, but maybe with some scenario like "run terminal and execute app in it". Try to google something like this.
