Hi all, I just tried compiling lm_sensors-2.6.4. This didn't quite work: gcc -DMODVERSIONS -include /usr/src/linux/include/linux/modversions.h -D__KERNEL__ -DMODULE -DEXPORT_SYMTAB -fomit-frame-pointer -I. -Ikernel/include -I/usr/local/include -I/usr/src/linux/include -O2 -c kernel/busses/i2c-ali1535.c -o kernel/busses/i2c-ali1535.o kernel/busses/i2c-ali1535.c:183: `I2C_HW_SMBUS_ALI1535' undeclared here (not in a function) kernel/busses/i2c-ali1535.c:183: initializer element is not constant kernel/busses/i2c-ali1535.c:183: (near initialization for `ali1535_adapter.id') make: *** [kernel/busses/i2c-ali1535.o] Fehler 1 root at andi:/usr/src/system/lm_sensors-2.6.4# This is because I have an old i2c.h header in /usr/local/include. Why do you specify /usr/local/include before /usr/src/linux/include ?? In this case it was fatal. I guess you can safely assume that /usr/src/linux is the most recent tree. BTW: Bus 0, device 0, function 1: IDE interface: Silicon Integrated Systems [SiS] 5513 [IDE] (rev 208). IRQ 14. Master Capable. Latency=64. I/O at 0x4000 [0x400f]. Bus 0, device 1, function 0: ISA bridge: Silicon Integrated Systems [SiS] 85C503/5513 (rev 1). And on another system: Bus 0, device 2, function 0: ISA bridge: Silicon Integrated Systems [SiS] 85C503/5513 (rev 0). Bus 0, device 2, function 3: USB Controller: Silicon Integrated Systems [SiS] 7001 (#2) (rev 7). IRQ 11. Master Capable. Latency=64. Max Lat=80. Non-prefetchable 32 bit memory at 0xcffff000 [0xcfffffff]. Bus 0, device 2, function 2: USB Controller: Silicon Integrated Systems [SiS] 7001 (rev 7). IRQ 5. Master Capable. Latency=64. Max Lat=80. Non-prefetchable 32 bit memory at 0xcfffe000 [0xcfffefff]. Bus 0, device 2, function 5: IDE interface: Silicon Integrated Systems [SiS] 5513 [IDE] (rev 208). Master Capable. Latency=16. I/O at 0xff00 [0xff0f]. See ? I'm an "SiS only" house (well, not quite). :-) (this is a GA586SGX and K7S5A, respectively) BTW, I've even got 5595 chipset specs !!! Needless to say I'll try to have a go about the 5511/12/13 misdetection issue. Have fun ! -- Andreas Mohr Stauferstr. 6, D-71272 Renningen, Germany Tel. +49 7159 800604 http://mohr.de.tt
