Comment:

 Replying to [ticket:298 dwmw2]:
 > When I boot from the internal NAND flash, I see udev timeouts at boot
 and the wireless device constantly appearing and disappearing from the bus
 (as mentioned in the second comment in ticket 278).
 >
 > This may well be a hardware issue -- I don't see why the software should
 cause this.
 >
 > There exists a _possibility_ that I only saw this when trying to use the
 new driver with the old boot2 firmware (cf. ticket 285) but I think I've
 seen it even with new boot firmware. Will confirm in the morning and
 provide USB traces of the observed behaviour.

 I'm having a similar problem where the device simply disappears, power
 cycle usually fixes the situation. Dan has also seen it happen:


 -bash-3.1# ls /sys/bus/usb/devices/

 1-0:1.0  1-1  1-1:1.0  2-0:1.0  usb1  usb2

 After powercycle:

 -bash-3.1# uname -a

 Linux localhost.localdomain 2.6.19-rc1 #1 Fri Oct 27 23:42:34 BST 2006
 i586 i586 i386 GNU/Linux
 -bash-3.1# ls /sys/bus/usb/devices/

 1-0:1.0  1-1  1-1:1.0  1-4  1-4:1.0  2-0:1.0  usb1  usb2
