Hi, we have a couple of 4.4-RELEASE machines that have both Intel 82801AA (ICH) SMBus controllers and BrookTree 878 TV cards. Both of these attach to smbus devices, the BrookTree to smbus0 and the Intel to smbus1. The problem is that all system status utilities I tried (wmhm, wmlmmon, etc.) access smbus0, which is the TV card, causing a kernel hang. Is there any way to force the Intel controller to attach to smbus0 instead? (I could patch the source of the utilities, but they need to be able to run on "standard" machines as well.) Here's the relevant dmesg output: bktr0: <BrookTree 878> mem 0xf6001000-0xf6001fff irq 13 at device 9.0 on pci2 iicbb0: <I2C generic bit-banging driver> on bti2c0 iicbus0: <Philips I2C bus> on iicbb0 master-only smbus0: <System Management Bus> on bti2c0 smb0: <SMBus general purpose I/O> on smbus0 bktr0: Hauppauge Model 61381 D423 bktr0: Detected a MSP3430G-A4 at 0x80 bktr0: Hauppauge WinCast/TV, Philips FR1236 NTSC FM tuner, msp3400c stereo, remote control. ichsmb0: <Intel 82801AA (ICH) SMBus controller> port 0xdcd0-0xdcdf irq 13 at device 31.3 on pci0 smbus1: <System Management Bus> on ichsmb0 smb1: <SMBus general purpose I/O> on smbus1 Thanks, Lars -- Lars Eggert <larse@isi.edu> Information Sciences Institute http://www.isi.edu/larse/ University of Southern California To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
