Tried to use lm_sensors-2.6.2 (compiled with gcc-3.0.3 release) with kernel-2.4.18-pre7 (also compiled with gcc-3.0.3). It took some minutes to load lm_sensors kernel modules, but sensors semmed to work after that. Adding -fno-strict-aliasing to modules compile options fixed that bad behaviour: --- Makefile~1 Sat Jun 2 06:41:17 2001 +++ Makefile Mon Jan 28 10:32:01 2002 @@ -170,7 +170,7 @@ -Wcast-align -Wwrite-strings -Wnested-externs -Winline endif -MODCFLAGS := $(CFLAGS) -D__KERNEL__ -DMODULE -fomit-frame-pointer +MODCFLAGS := $(CFLAGS) -D__KERNEL__ -DMODULE -fomit-frame-pointer -fno-strict-aliasing MODCFLAGS := $(MODCFLAGS) -DEXPORT_SYMTAB PROGCFLAGS := $(CFLAGS) ARCFLAGS := $(CFLAGS) Below is what I see in dmesg (simply for info what parts are actually in use) Andris i2c-i810.o version 2.6.2 (20011118) i2c-i810.o: i810/i815 found. i2c-dev.o: Registered 'I810/I815 I2C Adapter' as minor 0 i2c-core.o: adapter I810/I815 I2C Adapter registered as adapter 0. i2c-i810.o: I810/I815 I2C bus initialized i2c-dev.o: Registered 'I810/I815 DDC Adapter' as minor 1 i2c-core.o: adapter I810/I815 DDC Adapter registered as adapter 1. i2c-i810.o: I810/I815 DDC bus initialized i2c-i801.o version 2.6.2 (20011118) i2c-dev.o: Registered 'SMBus I801 adapter at e800' as minor 2 i2c-core.o: adapter SMBus I801 adapter at e800 registered as adapter 2. i2c-i801.o: I801 bus detected and initialized w83781d.o version 2.6.2 (20011118) i2c-core.o: driver W83781D sensor driver registered. i2c-core.o: client [AS99127F chip] registered to adapter [SMBus I801 adapter at e800](pos. 0). i2c-core.o: client [AS99127F subclient] registered to adapter [SMBus I801 adapter at e800](pos. 1). i2c-core.o: client [AS99127F subclient] registered to adapter [SMBus I801 adapter at e800](pos. 2). bash-2.05$ sensors as99127f-i2c-2-2d Adapter: SMBus I801 adapter at e800 Algorithm: Non-I2C SMBus adapter VCore 1: +1.64 V (min = +1.56 V, max = +1.72 V) +3.3V: +3.45 V (min = +3.13 V, max = +3.45 V) +5V: +5.04 V (min = +4.72 V, max = +5.24 V) +12V: +11.36 V (min = +10.79 V, max = +13.19 V) -12V: -11.48 V (min = -10.73 V, max = -13.19 V) -5V: -4.98 V (min = -4.74 V, max = -5.24 V) fan1: 4115 RPM (min = 1500 RPM, div = 4) temp1: +30?C (limit = +60?C, hysteresis = +50?C) temp2: +35.5?C (limit = +67?C, hysteresis = +60?C) vid: +1.65 V alarms: Chassis intrusion detection
