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.

Hello,
The other network drivers were previously compiled as modules, and I
only had apne built-in.
Now I removed the other drivers being built in any way, but I still get
an error:

The error is a bit different, and seems to happen at an earlier stage
than the previously reported one, since parport and gayle are not yet
inserted.
The end of dmesg output is again:
...

These outputs are from a cross-compiled linux 3.0.0.
