[BUG][2.6.5 final][e100/ee100pro] NETDEV_WATCHDOG Timeout - Related to i2c interface?

[Shawn Starr]

Ok, did disable ACPI but still get these errors. I have noticed that if I
start loading/unloading any i2c drivers I start getting eth0 timeouts....the
question is why?

Yes, sorry.  Can't believe I posted that to lkml.  Oh well.
