Next adapter: SMBus PIIX4 adapter port 0 at 0b00 (i2c-2) Next adapter: Synopsys DesignWare I2C adapter (i2c-1) Next adapter: Synopsys DesignWare I2C adapter (i2c-0)ĭo you want to scan it? (YES/no/selectively): YESĪdapter doesn't support all probing functions.Ĭlient at address 0x2c can not be probed - unload all client drivers first! Using driver `i2c-piix4' for device 0000:00:14.0: AMD KERNCZ SMBus

Reasonably well on most systems, it has been reported to cause troubleĭo you want to probe the I2C/SMBus adapters now? (YES/no): YES This is the most risky part, and while it works Lastly, we can probe the I2C/SMBus adapters for connected hardware ISA slots! Do you want to scan the ISA I/O ports? (YES/no): YES Yes, you do have ISA I/O ports even if you do not have any We have to write to arbitrary I/O ports to probe them. Some hardware monitoring chips are accessible through the ISA I/O ports. This is usually safe.ĭo you want to scan for Super I/O sensors? (YES/no): YES Some Super I/O chips contain embedded sensors. (YES/no): YESĪMD Family 12h and 14h thermal sensors. Some south bridges, CPUs or memory controllers contain embedded sensors.ĭo you want to scan for them? This is totally safe. It is generally safeĪnd recommended to accept the default answers to all questions, To load to use lm_sensors most effectively. This program will help you determine which kernel modules you need # Processor: AMD Ryzen 5 3500U with Radeon Vega Mobile Gfx (23/24/1) usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed Physically verify that the fans have been to full speed However, it is ** very important ** that you The program will attempt to restore each fan to full speedĪfter testing. We will attempt to briefly stop each fan using the pwm controls. Note that many motherboards do not have pwmĬircuitry installed, even if your sensor chip supports pwm. This program will search your sensors for pulse width modulation (pwm)Ĭontrols, and test each one to see if it controls a fan on I am providing the Terminal Readout below for more clarity on the issue. Tried setting up fancontrol on the system but I'm unable to as it says there is no pwmconfig file. Hi I have just installed Ubuntu 20.04 on a new laptop but the fans are out of control.
