See AMDGPU#Flickering_and_white_screens for resolution.

ELAN I2C touch pad not working


AMDI0010 I2C should be in dmesg.

PCIe Bus Error for nvme

PCIe Bus Error: severity=Corrected, type=Physical Layer, id=00e5(Receiver ID)

Due to PCIe Active State Power Management that is transitioning the link to a lower power state and maybe causing the device to trigger these errors. Using the pcie_aspm=off boot parameter could solve this problem but increase the power consumption as it disables the power savings.


Speaker no sound

  • Check kernel version, should above 6.3.8
  • Make sure i2cdetect -r -a 1 shows devices on address 40 and 42.
  • Make sure hwinfo | grep CSC3551 shows modalias = "acpi:CSC3551:", driver = "Serial bus multi instantiate pseudo device driver"
  • Make sure hwinfo | grep cs35l41-hda shows cs35l41-hda: module = snd_hda_scodec_cs35l41_i2c

Mute/micmute LEDs does not lit

The kernel version must be greater than or equal to 6.4.6, and upgrading the kernel to 6.4.6 will work normally.

Suspend does not work

This laptop lacks support for classic S3 suspend, It only supports S2 suspend mode. Regarding the suspend mode, with the help of Mario Limonciello, after enabling CONFIG_AMD_PMC (kernel 6.4.6), I tested suspend and wake up separately, and it has worked normally.
