Description Justin Hibbits 2015-01-06 20:48:01 UTC
The PowerPC loader doesn't currently support writing to disk from the loader. This causes 'nextboot -k' to always boot the next kernel, unless explicitly unloaded, whereas on i386 once the test kernel is loaded, the behavior is reverted back to the default kernel, in case of failure. On powerpc (32-bit) the kernel can be unloaded, which reduces the impact of this issue, but on powerpc64, unloading the kernel doesn't completely work, so loading a new kernel does not work, and panics or load failures ensue. Of course, this itself should be fixed, to allow unloading, but that's another problem entirely.
