 Hi
 
 After checks on other systems, it seems that the IXP SMBus controller =
 should not be recognized by ichsmb but by intpm. I tried changing the =
 declarations in intpm to add its PCI ID and, by loading intpm manually =
 afterwards, the resources of the device are correctly allocated. Problem =
 is that implementation seems incomplete, as SMI mode is not supported in =
 intpm, and driver still doesn't attach.=20
 
 I patched intpm.c this way to make it recognize the controller :
 
 98a99,101
 >       case 0x43721002:
 >               device_set_desc(dev, "ATI IXP400 SMBus Controller");
 >               break;
 
 When module is loaded, this output is displayed :
 
 Aug 12 19:42:31 milkyway kernel: intsmb0: <ATI IXP400 SMBUS Controller =
 (by KindMan)> port 0x900-0x90f at device 20.0 on pci0
 Aug 12 19:42:31 milkyway kernel: intsmb0: intr SMI enabled revision 0
 Aug 12 19:42:31 milkyway kernel: intsmb0: Unsupported interrupt mode
 Aug 12 19:42:31 milkyway kernel: device_attach: intsmb0 attach returned =
 6
 
 Thanks for your help,
 Aur=E9lien
