I'm trying to use another kernel and I can't seem to get it right. I keep getting the "failed to load kernel 'phatk'" message in the console.
Kernels developed for Phoenix 1.x are not directly compatible with Phoenix 2, but the required changes are minimal.
If the phatk kernel were updated to be compatible, it would work. I can't think of any benefit to doing so, though. The phatk2 kernel outperforms phatk on all hardware we've tested with.
