Hello All,

I tried current CVS HEAD plus the patches from
ftp://ftp.linux-mips.org/pub/linux/mips/people/skylark/
on an SMP Octane with 2x195 MHz R10000 and ESI graphics.

Results:

- Local console works.
- IOC3 networking works, with 2MB/s maximum for a 30MB http transfer
- Serial console works, but start of output is delayed. The driver
  probably lacks transfer bootstrap, and starts transmisssion only when
  the first buffer is full.
- Rebooting for SMP works, but this patch apparently broke arcload (hangs
  after "Entering Kernel").
- Serial console and framebuffer initializations seem to be mutually
  exclusive, that's impractical if you plan to route console (debug)
  output over serial while working on the graphics console.
- 'echo "foo" >/dev/fb0' kills the machine.

The dmesg for a serial boot is appended.
