Bug #607: lenovo R60  SMP/APIC_IO woes

Author: Andrew Atrens
Status: Closed
Priority: Normal
Target version: 

Hey Folks,

Just got a IBM ThinkPad R60 ... it's got a "Centrino Duo" dual core processor, so I thought I'd
try an SMP kernel ..

. and interrupt delivery does not work for bge0, neither does sound, nor disk (when I'm in AHCI
mode, in bios compatibility mode (UDMA33) it does work).

Symptoms are - bge0 watchdog timeouts, with ethereal I see TX's on the wire - but can't receive
any packets. sound doesn't work  pcm0:play:0:dsp0.0: play interrupt timeout, channel dead. for
the disk, controller is detected, but no disks found.

All in all, pretty broken. :(

Oh, EST is broken, too, but that's because the CPU runs at 1.66GHz and the cpu reports as -
hw.model: Genuine Intel(R) CPU           T2300  @ 1.66GHz

I suspect this cpu is supported on NetBSD, I'll take a shot at merging the newer NetBSD version ...

Would dearly love to be able to turn up the second core on this puppy! :)
