Following up the problem reported by few people running Sony VAIO FX
series (601, 604 models with VIA chipsets) I made a little research.
When the pcm driver is attached with the help of snd_via82c686.ko module
(loaded via loader) the sound card (chip1) gets properly detected as
pcm0.
However, the whole thing stops when the configure() routine enables
interrupts. Indeed, we are flooded with interrupts (via_intr() is
getting called over and over). I've checked in VIA chip registers, the
both sound card and integrated winmodem are not requesting interrupts
at this time. I've written a small stub driver attaching to a winmodem
(just printf() in the interrupt routine). This looks to me like VGA
interrupt coming over and over.
The problem is, that the only useful setting in BIOS is "PnP OS", one
cannot distable VGA IRQ apparently.
1) Is FreeBSD in UP mode really sharing IRQs? (can't boot MP kernel on
this notebook)
2) Why when NO driver is attached to the irq 5 the system works
properly?
Unfortunately, my PCI knowledge is very poor, and I got so far only
thanks to the excellent VIA chipset docs.
BTW. -current installation kernel crashes at startup, however some
reported success via the source upgrade (no problems with pcm).
