Outstanding problems with LG monitor Thunderbolt stability / GPU hangs

Framework Laptop 16
,

Literally as I was writing the last updates it hanged again, so it seems that none of the known remediations work for me now.

Anything electron-based seen to be triggering the hang after few moments of using it. Laptop in this form is literally unusable.

There are no page fault logs from the last crash, probably because I already power-cycled the laptop quickly and they didn’t flush on time. I’m done waiting for recovery that never happens.

FWIW my current setup:

  • vanilla kernel 6.18.3
  • MES firmware 0x80 (pulled all the new firmware from amdgpu/ folder of linux-firmware repository
  • amdgpu.cwsr_enable=0 in commandline
  • GPU configured to have 8GB of memory (I have no idea what’s causing the page fault, but seem memory related)

I’m using internal laptop screen and external Thunderbolt screen attached via Thunderbolt4/USB4 docking station.
