--- Comment #18 from Dave (thefe...@gmail.com) --- (In reply to Thanathan from comment #3) > Additionally I lost gui/tui output shortly after the kernel was loaded, > including ttys. Reverting to linux-firmware 20190424.4b and rebuilding > initramfs fixed the issues. I have found that I get similar hangs when the GPU is in the lowest clock / memory clock state, as well as the highest state. Disabling these two states via: echo "manual" > /sys/class/drm/card0/device/power_dpm_force_performance_level echo "2 3" > /sys/class/drm/card0/device/pp_dpm_mclk echo "3 4 5 6" > /sys/class/drm/card0/device/pp_dpm_sclk Allows the laptop to avoid these hangs with the updated firmware (though at a performance loss and higher idle power.) I also noticed that these hangs are a reliable way to trigger the power issue, where the cord isn't recognized, as it persists after boot (sometimes for two or three boots before it is recognized again.) Additionally, this problem only appears after boot - while waiting at the dmcrypt prompt, for instance, power is always detected normally. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ acpi-bugzilla mailing list acpi-bugzilla@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
