Hey all! I've just set up boxes with FreeBSD 6.2 (currently not running stable yet, but will in a day or so), and as the motherboard is a VIA-based something (with a VIA C3 CPU), I thought that viapm should be the appropriate driver to enable smbus for lmmon and the like. Anyway, the driver loads fine: --- viapropm0: SMBus I/O base at 0x6000 viapropm0: SMBus I/O base at 0x6000 viapropm0: <VIA VT82C686A Power Management Unit> port 0x6000-0x600f at device 7.4 on pci0 viapropm0: SMBus revision code 0x40 smbus0: <System Management Bus> on viapropm0 smb0: <SMBus generic I/O> on smbus0 --- (this is loaded after boot has completed, because I didn't yet have it in loader.conf, but I don't presume this has any impact on the usability of the driver). /dev/smb0 is properly created, but when I then try to run lmmon, the output is the following: --- goettingen01# lmmon IOCTL: Device busy goettingen01# --- I've looked through Google, trying to find some info, but I don't really see much that would help me set this up, that's why I'm mailing this list.

Are you sure your moinboard does contain monitoring
hardware that is supported by lmmon?
I have a very similar VIA C3 system on an EPIA PD10K
mainboard. The viapm driver supports it fine, but
it doesn't have lmmon-supported monitoring hardware,
unfortunately. Here's dmesg, pciconf and sysctl
output if you're interested:
