Correction, only one 'hose0' on the 1000a, problem seems to be : hose0
slot8 DEC chip 21050-AA bridge to bus 2, PCI-PCI. Cards plugged in to
these 4 pci slots are not initialized by kernel. The scsi controller
Qlogic ISP10x0 is also located here -hose0 bus 2..On boot your netbsd
kernel stops at : root file system type: ffs machine hangs here. My
kernel built from 1.5Usources will boot, with a PBXGA-AA card plugged
into one of these slots i get a kernel panic with :
root file system type: ffs
panic: cnopen: cn_tab->cn_dev==NODEV
stopped in pid >(init) at cpu_debugger +0x4 ret zero,(ra)
I added a USB (2-port Opti chip) pci card to this slot and i can boot
but i get the following dmesg:
