Charger state is already handled by ACPI_AC. Thanks for the tag! My series aims to reduce the pressure on the broken mutex and hence reduce = the probability of triggering the mutex bug. It cannot miraculously fix all dme= sg spamming. As long as it reduces some dmesg messages and/or system freeze, it works as expected. A proper fix will be a BIOS update, but unfortunately we haven't heard good news about it. And it seems that whether seeing the ucsi_acpi spamming depends on models. = Some folks in the thread rarely see it while others see it more frequently, IIRC. I actually tried to submit a patch to disable ucsi_acpi on devices with the mutex bug. It is never merged as Mark wanted some more time for the FW team= to investigate the issue. --=20 You may reply to this email to add a comment.
