I have a crusty ancient laptop I am using to control my sprinkler system. I=
=20
was going to use a PCMCIA ethernet controller but the slot is hosed, so I g=
ot=20
a USB ethernet adapter (LinkSys USB200M) which is driven by if_axe.

I works reasonably well, but fairly frequently I get..
axe0: watchdog timeout
axe0: usb error on tx: TIMEOUT

If I unplug/replug the device it works again, or if I bring the interface d=
own=20
then up.

The USB controller and axe dmesg bits are as follows..

ohci0: <NEC uPD 9210 USB controller> mem 0xf7fff000-0xf7ffffff irq 11 at=20
device 11.0 on pci0
ohci0: [GIANT-LOCKED]
usb0: OHCI version 1.0
usb0: <NEC uPD 9210 USB controller> on ohci0
usb0: USB revision 1.0
uhub0: NEC OHCI root hub, class 9/0, rev 1.00/1.00, addr 1
uhub0: 2 ports with 2 removable, self powered
axe0: Linksys USB 2.0 10/100 ethernet controller, rev 2.00/0.01, addr 2
miibus0: <MII bus> on axe0
rlphy0: <RTL8201L 10/100 media interface> on miibus0
rlphy0:  10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto
axe0: Ethernet address: 00:10:60:84:09:bd
axe0: if_start running deferred for Giant

This is on a Toshiba Satellite 2540CDS, I've attached the full dmesg, kern=
=20
conf, etc.

Anyone have any suggestions?
