As for debugging, I compiled kernel with: makeoptions DEBUG=-g options KDB options KDB_TRACE options DDB To have coredump, if system crashes (I didn't oticed any slowdown, so I guess it doesn't hurt) Are those last three options necessary to get core? Or is only DEBUG=-g needed? -- Best regards, Derek mailto:takeda@takeda.tk CCNA, SCSA, SCNA, LPIC, MCP certified http://www.takeda.tk Trying to outsmart a compiler defeats much of the purpose of using one. -- Kernighan & Plauger, "The Elements of Programming Style"
