Dear all,
I've a very urgent question that, when I install FreeBSD 5.0-RELEASE
(sparc64) on my SunFire V100, the network interface cards cannot be
detected. After I've loaded or re-compiled the kernel for the if_dc
module support, it can detect my network cards (Davicom DM9102A) but
the MAC address cannot be detected.
When I try to up the dc0 or dc1, the machine will report to me there
is DMA uncorrectable error and reboot.
Does anyone know how to solve this problem and bring up my network
cards?
