Thanks for testing it on both the boards. Good to hear it works.

That is weird. The log file you sent is 38819 bytes. I would expect the
boot time penalty to be not much more than the I/O time of 38819 bytes /
(11520 bytes/second) = 3.37 seconds. I did a test with loglevel 8. It
logged
45745 bytes and the boot time from cold reset to DOS prompt was 5.56
seconds. When I watch the serial output, it spews text nearly
continuously.
There is no hardware or software handshaking for the writes, so nothing
should slow it down.

I see, I had tested only a small memory configuration so far. It looks
like any size greater than 4GB will fail. Try the attached patch.
Works great, 3.5gb of available RAM. I've submitted it into the review
system.
Thanks,
Scott
Thanks again!

Okay, There's something odd going on here. Now the NIC is gone. I'm
going to investigate in the morning and abandon the change in gerrit
until I know what's going on.
