Hi The thinkpad_acpi driver constantly reports about unhandled events on my ThinkPad X1 5gen. The logs look like this: kernel: thinkpad_acpi: unknown possible thermal alarm or keyboard event received kernel: thinkpad_acpi: unhandled HKEY event 0x60b1 kernel: thinkpad_acpi: please report the conditions when this event happened to ibm-acpi-devel@... kernel: thinkpad_acpi: unknown possible thermal alarm or keyboard event received kernel: thinkpad_acpi: unhandled HKEY event 0x60b0 kernel: thinkpad_acpi: please report the conditions when this event happened to ibm-acpi-devel@... I have no clue what triggers them. However, the 0x60b1 event seems to notify about some kind of action, and 0x60b0 seems to notify about its end (like FAN-START, and FAN-STOP). The 0x60b0 follows 0x60b1 usually in a timespan between 1s-10s. The event occurs even when the laptop is not moved/touched, but only performs random computations. The first time this occurs is usually during user-space startup, which might just be the time the module is loaded. So far, I did not see any other event occurring before/after it, which might give any hints. What is the recommended way to deal with that? I am having a hard-time figuring out what triggers it, but at the same time it spams the system-logs to a degree that after 1h of uptime, the vast majority of the system log is cluttered with those messages. I can provide a patch to ignore these events in the driver? Or does anyone have access to Lenovo developers to ask for help? Thanks David
