I apparently have a system with a bios that doesn't play well with linux.
Laptop - Sony Vaio GRX 570 i8x0 The only problems I'm having are with audio (ac97_codec), and the modem (hcf).
The sound is choppy.
And the modem just won't work (drivers installed). All modules load clean when I try to access the modems dev with minicom or ppp but it won't communicate. I'm just guessing because it doesn't get assigned an IRQ.
I've tried booting with the pci=biosirq parm with no luck. If anyone has any ideas what I can do, thanks.
