We are running 2.4.6 kernel from kernel.org.
The latest kernel opn Monta Vista side did not work at all on MCP750 and on
our custom 8260 based board. Kernel woud start, but none of rhe external
interfaces would work (console, Ethernet). Eventually (by flashing LEDs on
our board) I traced it down to the transmit section of console code. It will
sit in the endless loop waiting for Tx buffer go empty. Looks like
interrupts were disabled by some reason.

Anyway, we downloaded latest 2.4.6 from kernel.org This works fine on our
8260 board.
We use MCP750 REV.A board
