First time I've tried to access smb devices or used mbmon, so apologies if this is very stupid. Running 6.0-stable (from awhile ago, December) on an Intel server motherboard. In the boot dmesg I get this line: pci0: <serial bus, SMBus> at device 31.3 (no driver attached) I have nothing relating to SMB compiled in my kernel. I do "kldload ichsmb" ichsmb0: <Intel 6300ESB (ICH) SMBus controller> port 0x400-0x41f irq 17 at device 31.3 on pci0 ichsmb0: [GIANT-LOCKED] smbus0: <System Management Bus> on ichsmb0 then "kldload smb" smb1: <SMBus generic I/O> on smbus0 smb0: <SMBus generic I/O> on smbus0 There are now the twoce devices in /dev, however, whenever I try to run mbmon I get # mbmon -S -s0 -d ioctl(smb0:writebyte): Device not configured (same result for s1 to try smb1) If I unload all the SMB related modules and run mbmon, I get # mbmon -d ioctl(smb0:open): No such file or directory SMBus[Intel8XX(ICH/ICH2/ICH3/ICH4/ICH5/ICH6)] found, but No HWM available on it!! Using ISA-IO access method!! * Winbond Chip W83627HF/THF/THF-A found. and just running mbmon gives an output # mbmon ioctl(smb0:open): No such file or directory Temp.= 127.0, 115.0, 127.0; Rot.= 0, 1834, 2812 Vcore = 0.00, 1.17; Volt. = 3.33, 5.00, 12.22, 1.62, 0.23 [etc] So I'm not sure what's going on. Is the existence of smb devices important? Do I get better monitoring? Scott
