I made three tests: - STGT (with standard Debian Lenny kernel) - SCST with default build options (i.e. no "make debug2perf"), no kernel patches (standard Debian Lenny kernel) - SCST + "make debug2perf", with kernel patches (Debian Lenny .config + SCST patches and proper option enabled) I'll post the results shortly. -- Tomasz Chmielewski http://wpkg.org -- To unsubscribe from this list: send the line "unsubscribe stgt" in the body of a message to majordomo at vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html |
