as for the devinfo, here it is:
# devinfo -rv | grep rgephy
rgephy0 pnpinfo oui=0x732 model=0x11 rev=0x2 at phyno=1
now all of the boxes which were trasfered to that motherboard shows the same simptoms :( ...
and what i have to add is that external card doesn't show this behaviour! :(
on the ather box with the same hardware but additional nic:
# devinfo -rv | grep rgephy
rgephy0 pnpinfo oui=0x732 model=0x11 rev=0x2 at phyno=1
rgephy1 pnpinfo oui=0x732 model=0x11 rev=0x3 at phyno=1
# pciconf -lcv

device = 'dlg10028 Used on DGE-528T Gigabit adaptor'
