I think I've fixed many unresolved vr(4) issues but it needs more testing. You can download the overhauled vr(4) at the following URL. http://people.freebsd.org/~yongari/vr/if_vr.c http://people.freebsd.org/~yongari/vr/if_vrreg.h Note, don't use the overhauled driver on your production system. I couldn't see any issues in the driver but it may have unnoticed bugs. -- Regards, Pyun YongHyeon
