via_rhine: v1.10-LK1.5.0 2010-10-09 Written by Donald Becker mv643xx_eth: MV-643xx 10/100/1000 ethernet driver version 1.4 uhci_hcd 0000:00:0c.2: irq 9, io base 0x00001040 sysfs: cannot create duplicate filename '/class/mdio_bus/0'
I have 2 Pegasos running 3.0, but in my case mv643xx_eth is non-modular and /sys/class/mdio_bus/0 exists and points to ../../devices/platform/mv643xx_eth.0/mdio_bus/0 which is correct as far as I can say. Is it a regression from 3.0 or not? Try to make it non modular and see what happens. If it is a regression, could you try to bisect it? I won't be close enough to the machines to do a regression hunt myself before a week or 3 (really, maybe next week, I don't yet know, but for sure starting on Nov 8th).
