Hi, In case anyone is still interested in testing OpenBSD on the Linksys NSLU2 (IXP42x). Source is available at the bottom of the page at http://lwazi.ca/openbsd/nslu2. The port is not complete - RTC, LED's, reset and power button not yet supported. I have to login to shutdown. If you know of another IXP42x port please let me know. I have pasted the dmesg at the end. One more thing, you have to go hunting for the firmware or remove NPE support.
Thanks, Lwazi OpenBSD 5.0 (NSLU2) #391: Sun Jan 1 13:45:56 MST 2012 lwazi@tbox:/usr/src/sys/arch/nslu2/compile/NSLU2 real mem = 33554432 (32MB) avail mem = 27095040 (25MB) mainbus0 at root cpu0 at mainbus0: IXP425 266MHz rev 1 (XScale core) cpu0: DC enabled IC enabled WB enabled LABT branch prediction enabled cpu0: 32KB(32b/l,32way) I-cache, 32KB(32b/l,32way) wr-back-lock D-cache ixpio0 at mainbus0 ixpip0 at ixpio0 ixpintc0 at ixpip0 addr 0xc8003000: Interrupt Controller ixpost0 at ixpip0 addr 0xc8005000 ixpost0: IXP425 Interval Timer com0 at ixpip0 addr 0xf0000000 intr 15: pxa2x0, 32 byte fifo com0: console ixme0 at ixpio0: IXP4xx MicroEngine Support ixpnpe0 at ixme0 NPE-B npe0 at ixpnpe0: Ethernet co-processor npe0: remember to fix rx q setup npe0: Ethernet address 55:44:33:22:11:00 rlphy0 at npe0 phy 1: RTL8201L 10/100 PHY, rev. 1 pci0 at ixpio0 bus 0 ohci0 at pci0 dev 1 function 0 "NEC USB" rev 0x43: INTA, version 1.0 ohci1 at pci0 dev 1 function 1 "NEC USB" rev 0x43: INTB, version 1.0 ehci0 at pci0 dev 1 function 2 "NEC USB" rev 0x04: INTC usb0 at ehci0: USB revision 2.0 uhub0 at usb0 "NEC EHCI root hub" rev 2.00/1.00 addr 1 usb1 at ohci0: USB revision 1.0 uhub1 at usb1 "NEC OHCI root hub" rev 1.00/1.00 addr 1 usb2 at ohci1: USB revision 1.0 uhub2 at usb2 "NEC OHCI root hub" rev 1.00/1.00 addr 1 ixpnpe0: ixpnpe_intr: status 0x60000 /dev/ksyms: Symbol table not valid. uhub3 at uhub0 port 2 "vendor 0x05e3 USB2.0 Hub" rev 2.00/77.61 addr 2 ural0 at uhub3 port 2 "Cisco-Linksys Wireless-G USB Network Adapter" rev 2.00/0.04 addr 3 ural0: MAC/BBP RT2571 (rev 0x05), RF RT2526, address 00:11:22:33:44:55 umass0 at uhub3 port 3 configuration 1 interface 0 "ITE TECH.
