This jams my PCG-F190 at probe time. I get
> pci0: <NeoMagic MagicMedia 256AV SVGA controller> at 8.0 irq 9
> pcm0: <NeoMagic 256AV> mem 0xfec00000-0xfecfffff,0xfe000000-0xfe3fffff irq 9 at device 8.1 on pci0
And then a lock-up. When I apply the attached patch, things work for
a while, but the machine seems keen on hanging still....
FWIW, the proble line that never happens when ac97_initmixer() is
called is:
> chip2: <Sony CXD1847A FireWire Host Controller> mem 0xfe7ffc00-0xfe7ffdff irq 9 at device 9.0 on pci0
Any suggestions ?
