--- Comment #6 from Michel Dänzer michel@daenzer.net --- (In reply to Darren from comment #5)
Sadly, as of thus far, every kernel I've compiled panics at bootup, with a message like this, or similar: "kernel panic. vfs unable to mount root on unknown block (0,0)".
Sounds like there's a problem with the .config or maybe the root=[...] parameter on the kernel command line. For .config, I'd recommend starting with the original .config from 4.3-rc7 and then just running "make oldconfig".
After I get the kernel to compile and boot, do I need to run "make clean" in the source tree directory after "git bisect good," or is that going to strip away files that git bisect needs in order to keep a record of good and bad commits?
make clean is neither necessary nor does it hurt (other than potentially increasing the build time of the next kernel to test).
