Well, it's definitely stable enough for lab use, that's a bonus. I caused m=
yself a few headaches by doing stupid things that caused a series of panics=
, but all are easily attributed to human errata...

Oddly the i2c bus is gone - any ideas what we changed that caused it to dis=
appear?

If I'm reading the DSDT correctly, then it should be hanging right off acpi=
0. We can even see it in an older dmesg.boot:

i2c0: <Vybrid Family Inter-Integrated Circuit (I2C)> iomem 0x2000000-0x200f=
fff irq 7 on acpi0

But now, nothing...

Aside - since the builtin netifs are basically useless for us, any suggesti=
ons on USB wifi dongles? I tried a few from my parts piles, but all of them=
 were unstable Realtek trash. I know Atheros chips are usually a good bet i=
n Linux land - does that hold true in FreeBSD as well?
