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.
