Hi,

the other witness warning which I promised to report
in my last email is actually a LOR which occurs on
ACPI shutdown/reboot/halt. I haven't seen it mentioned
in the LOR-list yet. Here the output. These are two
pages, so I wrote down only the essential info.

lock order reversal
1st vr0 _at_/usr/src/sys/pci/if_vr.c:806
2nd ACPI root bus
_at_/usr/src/sys/modules/acpi/acpi/../../../dev/acpica/acpi.c:1056
