[Voyage-linux] miniPCI express card USB disconnects when eth0 used

Teco Boot (spam-protected)
Thu Mar 18 19:57:28 HKT 2010 

I can report similar results, with Sierra MC8700 and Alix6e2 running Voyage 0.6.5.
I see it often 5 hours after reboot.
I do not relate this to eth0 (in my case).

Is the starting order of uhci_hcd and ohci_hcd important?
And USB interface number?

Currently, I use a watchdog script checking ttyUSB0 to ttyUSB3. When mismatch, the box is rebooted.

Regards, Teco

> I had contact with mr. Dornier from PCEngines, and we concluded that the Ethernet drivers possibly were to be suspected of this behaviour. The reason is that (for 0.6.2 at least), the base addresses found in ifconfig were conflicting with the addresses of other devices on the board. I can provide some documentation, but I'm not aware if it is accepted to attach files here.
