Hello NetBSD. I think this maybe related to msaitoh@ work in ./sys/dev/pci/*wm*. The latest kernel begins boot, then just hangs, last 3 lines are (transcribed):
wm0 at pci0 dev 25 function 0: PCH2 LAN (82579LM) controller (rev. 0x04) wm0: interrupting at msii vec 0 wm0: wm_init_lcd_from_nvm: need write_smbus() -bch
