Ever since I got hold of my Ultra 60 workstation I have been trying to get a Gigabit Ethernet PCI card working in it under NetBSD. But neither a 3Com 3C996B-T nor an Intel PRO/1000 MT card worked in that machine because of problems with PCI interrupts.
But thanks to Julian Coleman and Rafal Boni the problem got fixed finally. The Intel card is now working fine under NetBSD 4.99.52:
wm0 at pci1 dev 1 function 0: Intel i82540EM 1000BASE-T Ethernet, rev. 2
wm0: interrupting at ivec 0
wm0: 32-bit 66MHz PCI bus
wm0: 64 word (6 address bits) MicroWire EEPROM
wm0: Ethernet address 00:07:e9:XX:XX:XX
makphy0 at wm0 phy 1: Marvell 88E1011 Gigabit PHY, rev. 3
makphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseT, 1000baseT-FDX, auto
The network performance is not great yet but it is a step in the right direction. Now I wait impatiently until Martin Husemann finishes the work on SMP for NetBSD/sparc64.
