Hi, I set this up in a VirtualBox with 9-current r212073 amd64, 4-cores, amd-v and nested paging enabled. I tried dtruss /usr/bin/true it works but is really slow, it takes ~10s to switch vt. I tried the pid example as well, if I execute it on ttyv0 I can see lots of kernel trap 12 with interrupts disabled messages flying by and inbetween the desired _sleep:entry probes. When I execute that script on ttyv1 I obviously don't see the kernel trap messages and the machine kindof locks up (no output at all). I can do a clean ACPI shutdown though. - Marius _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
