Hi Jean, I finally got it running, but your p4b_smbus.o code is not SMP compliant. I compiled it successfully under a single processor kernel. Here comes what the module said, when inserting it under the SMP kernel again: # insmod p4b_smbus.o p4b_smbus.o: unresolved symbol pci_insert_device_R3341a12e p4b_smbus.o: unresolved symbol pci_read_config_word_R923654cb p4b_smbus.o: unresolved symbol pci_remove_device_R2d6c74a6 p4b_smbus.o: unresolved symbol kmalloc_R93d4cfe6 p4b_smbus.o: unresolved symbol pcibios_present_R520a75b9 p4b_smbus.o: unresolved symbol pci_find_device_Rc584f4e3 p4b_smbus.o: unresolved symbol pci_enable_device_R1bc741d2 p4b_smbus.o: unresolved symbol pci_write_config_word_Rf23d8795 p4b_smbus.o: unresolved symbol kfree_R037a0cba p4b_smbus.o: unresolved symbol printk_R1b7d4074 p4b_smbus.o: unresolved symbol pci_setup_device_R863ed348 When activating the SMBus I really didn't know what I was doing. I got the hex value 0049 and then changed it to 0040, like described in the README.p4b. The output of pcitweak was as followed: # setpci -d 8086:24c0 f2.w=40 # pcitweak -l PCI: Probing config type using method 1 PCI: Config type is 1 PCI: PCI scan (all values are in hex) PCI: 00:00:0: chip 8086,2560 card 1043,80b2 rev 02 class 06,00,00 hdr 00 PCI: 00:01:0: chip 8086,2561 card 0000,0000 rev 02 class 06,04,00 hdr 01 PCI: 00:1d:0: chip 8086,24c2 card 1043,8089 rev 02 class 0c,03,00 hdr 80 PCI: 00:1d:1: chip 8086,24c4 card 1043,8089 rev 02 class 0c,03,00 hdr 00 PCI: 00:1d:2: chip 8086,24c7 card 1043,8089 rev 02 class 0c,03,00 hdr 00 PCI: 00:1d:7: chip 8086,24cd card 1043,8089 rev 02 class 0c,03,20 hdr 00 PCI: 00:1e:0: chip 8086,244e card 0000,0000 rev 82 class 06,04,00 hdr 01 PCI: 00:1f:0: chip 8086,24c0 card 0000,0000 rev 02 class 06,01,00 hdr 80 PCI: 00:1f:1: chip 8086,24cb card 1043,8089 rev 02 class 01,01,8a hdr 00 PCI: 00:1f:3: chip 8086,24c3 card 1043,8089 rev 02 class 0c,05,00 hdr 00 PCI: 00:1f:5: chip 8086,24c5 card 1043,80b0 rev 02 class 04,01,00 hdr 00 PCI: 01:00:0: chip 10de,0253 card 1043,803f rev a3 class 03,00,00 hdr 00 PCI: 02:03:0: chip 1106,3044 card 1043,808a rev 80 class 0c,00,10 hdr 00 PCI: 02:05:0: chip 14e4,4401 card 1043,80a8 rev 01 class 02,00,00 hdr 00 PCI: End of PCI scan I hope you have all information to change the module code. Anyway, sensors works now under the single processor kernel. Best regards, Alexander Pohl
