Hi Rudolf, Jean, Can you give some hints now? Frankly I have no idea about this issue yet. It seems the SMI caused system hang? Hi Daniel, Yesterday I send the new datasheet to you. I received the reject mail from Jean just now, so let assume you have received the datasheet now :) In that mail I mentioned the SMI#/IRQ mask registers, how about set these mask? I'm trying to disable SMI. I'm hoping to get the read back value of these commands. i2cset -y 0 0x2c 0x43 0xff i2cset -y 0 0x2c 0x44 0x7f i2cset -y 0 0x2c 0x9c 0xff If it does not work, let use following command to try other SMI mode. Now the mode of your board is two time interrupt mode. i2cset -y 0 0x2c 0x4c 0x01 #comparator interrupt mode or i2cset -y 0 0x2c 0x4c 0x81 #One time interrupt mode Or BIOS will not let us do this too.... I don't know. Or the SMI is triggered by fan limit/ voltage limit... The fan 4/5/6 low limit of your MB is not 0. Try to set all your fan limit value to zero. i2cset -y 0 0x2c 0x3b 0xff i2cset -y 0 0x2c 0x3c 0xff i2cset -y 0 0x2c 0x3d 0xff i2cset -y 0 0x2c 0xbb 0xff i2cset -y 0 0x2c 0xbc 0xff i2cset -y 0 0x2c 0xbd 0xff i2cset -y 0 0x2c 0xbf 0xff > >> Is there a chance that you have test hardware available with the > >> w83792d chip where you could try to run the same commands that I did? > >> > > Yes, I have a board on hand; it's a C version chip. > > Your chip seems to behave differently from mine, but then again it is has '12' > as revision ID where my chip has '13'.
