SubjectPPC & 2.6.0-test3: wrong mem size & hang on ifconfig
I tried 2.6.0-test3 + todays BK on a Motorola Powerstack (Utah II, 300
MHz 604e). It's basically a PReP machine from Motorola.

2.4.22-rc2 works well. 2.6.0-test3+latest bk fails in 2 places.

1. Network interface is detected correctly but first ifconfig command
(even if it fails because of wrong arguments) hangs the machine. This is
with both tulip driver (new io+mmio or mmio or just plain pio, 3 modes
tried) and de4x5 driver (the card is a onboard 21140).

2. 2.4 detects full 64M of RAM, 2.6 detects only 32M of RAM.

The dmesgs are below. 2.4 has compiled-in ide (no drives), 2.6 has no
ide compiled in. Will try 2.6 with ide next but I don't believe it's the
issue.
