When I go to load the klds, I get the error # kldload dtraceall kldload: an error occurred while loading the module. Please check dmesg(8) for more details. # dmesg | tail -5 linker_load_file: Unsupported file type KLD profile.ko: depends on cyclic - not available or version mismatch linker_load_file: Unsupported file type KLD dtraceall.ko: depends on profile - not available or version mismatch linker_load_file: Unsupported file type if I try and load profile, or cyclic, I get KLD profile.ko: depends on cyclic - not available or version mismatch linker_load_file: Unsupported file type link_elf_obj: symbol cyclic_clock_func undefined linker_load_file: Unsupported file type link_elf_obj: symbol cyclic_clock_func undefined linker_load_file: Unsupported file type Googling around this seems to be a known problem going back some time and there are various patches posted, but I am not sure what the best way to proceed is ? This is only for a test box so I can try and better understand why RELENG9 is so much faster than RELENG10 for my particular applications. This is releng9 from today after a fresh buildworld/kernel ---Mike -- ------------------- Mike Tancsa, tel +1 519 651 3400 Sentex Communications, mike@sentex.net Providing Internet services since 1994 www.sentex.net Cambridge, Ontario Canada http://www.tancsa.com/
