That "7829" status isn't perfectly obvious?
I was *certain* that they covered that in kindergarten! ;->

Are there cases where the driver doesn't recover?

No, forcing the media type won't fix the problem. The chip stops
transmitting when it doesn't have link beat even with the forced media
The driver is configured to take action quickly in an attempt to restore
operation, assuming that something has gone wrong. Look for v1.14 soon,
reset a transceiver left set to fixed 10baseT (Ref: Alpha SRM boot bug)
emit a few more details if the driver resets the chip
