HEllo,
So i reported a bug with a pci bridge a while ago. On an Apu with a
pci to pci bridge over pci express.
Dmesg below
I use a recent snapshot
OpenBSD 5.6-current (GENERIC.MP) #610: Tue Nov 25 06:00:07 MST 2014
and assume the commit was in
The situation improved, as i can have the card running with bsd.mp for
more than a second. But on the second boot.
During the first boot i add the <vr3: restarting> kernel message when
asking for a lease on vr3. At this moment my not reliable serial usb
decide to do the classic freez. This time i was not able to get access
to the machine.
I am currently sending icmp trhough rl and vr and waiting for a problem.
bug mail objet was : <pci disconnection creates interfaces instabilities>
dmesg:
