(Will only print output > when something bad happens.) I built with KDTRACE_HOOKS, but dtrace still does not work. It fails to load the dtrace module. Console says: [ 8928.7630011] kobj_checksyms, 1013: [dtrace]: linker error: symbol `dtrace_smap_enable' not found [ 8928.7630011] kobj_checksyms, 1013: [dtrace]: linker error: symbol `dtrace_smap_disable' not found [ 8928.7630011] WARNING: module error: Unable to affix module `dtrace', error 8 Perhaps we could just try a bunch of printfs? -- Emmanuel Dreyfus [email protected]
