--- Comment #9 from m...@sentex.net --- (In reply to Eugene Grosbein from comment #7) Hi, apart from KDB_UNATTENDED these options are all part of a standard GENERIC kernel on HEAD, no ? I added that as well as BREAK_TO_DEBUGGER. The kernel does not (nor has it ever) panic. I start the compile, and the compile gets stuck during the build.
