[Voyage-linux] PCI errors on voyage/rb230

[Drew]

I'm having trouble with a wireless link dropping repeatedly, and found 
this in /var/log/messages, repeated many times:

Dec 11 10:21:53 AW1 kernel: eth1: PCI error 0x800000
Dec 11 10:21:53 AW1 last message repeated 15 times
Dec 11 10:21:53 AW1 kernel: eth0: PCI error 0x800000
Dec 11 10:21:53 AW1 kernel: eth1: PCI error 0x800000
Dec 11 10:21:53 AW1 last message repeated 7 times
Dec 11 10:21:53 AW1 kernel: eth0: PCI error 0x800000
Dec 11 10:21:53 AW1 kernel: wifi0: hardware error; reseting
Dec 11 10:21:53 AW1 kernel: wifi0: ath_reset: unable to reset hardware: 
'' (HAL status 0)

eth0 and eth1 are built in on the routerboard 230, and wifi0 (ath0) is a 
mini-pci emp-8602:

0000:00:0e.0 Ethernet controller: Atheros Communications, Inc. AR5413 
802.11abg NIC (rev 01)
        Subsystem: Atheros Communications, Inc. EnGenius EMP-8602 
(400mw) or Compex WLM54AG
        Flags: bus master, medium devsel, latency 168, IRQ 10
        Memory at febe0000 (32-bit, non-prefetchable) [size=64K]
        Capabilities: [44] Power Management version 2

This is running on a somewhat old voyage:
Linux AW1 2.6.15-486-voyage #1 PREEMPT Mon Mar 27 07:45:05 GMT 2006 i586 
GNU/Linux

Any suggestions?

Thanks!
