Hi, there is some kind of bad interaction between i2c-matroxfb in the kernel (2.4.21) patched with lm_sensors 2.6.5. I have everything compiled into the kernel (no modules), and when the Matrox I2C devices are registered at boot time, the machine hangs for over 3 minutes. Also, scanning the Matrox I2C buses (not the motherboard SMBus) with i2cdetect is very slow too. There is no such hang on boot in the vanilla 2.4.21 kernel (with no lm_sensors patch applied). In both cases, the kernel I2C code is used, and Matrox devices are detected correctly, it's just that it is sooo much faster without the lm_sensors drivers compiled into the kernel. Hardware: Biostar M6TBA motherboard (W83781D sensor chip), Matrox G400DH 32MB graphics card. (BTW, the supplied TV-out cable has the DDC pins SDA and SCL shorted. Does the kernel I2C code deal correctly such unusable I2C buses?) Is this a known problem? If there is anything I should check (I'm not brave enough to try the 2.5.x kernels with the latest lm_sensors just yet...), please tell me. Thanks! Marek
