This differs from the earlier bug report, where the kernel complained of 
"mismatched read page pointers". But the timeout is the same.

Perhaps you could build and test a new kernel with no DP8390-based driver 
except apne (probably easiest to disable all ethernet drivers except 
CONFIG_APNE).

Please let us know if that helps, as it may shed some light on the other 
bug too.
