Hi there, my terminal just asked me to report this, so here it goes: thinkpad_acpi logged the following lines. This happened pretty much exactly when i connected a power supply to my ThinkPad[0]. I was backing up a partition with clonezilla[1] at that time. ----- unknown possible thermal alarm or keyboard event received unhandled HKEY event 0x6040 please report the conditions when this event happened to ibm-acpi-devel@xxxxxxxxxxxxxxxxxxxxx EC reports that Thermal Table has changed ----- Nothing else happened, my backup went fine, the machine didn't freeze. Best wishes, Claudius [0]: Lenovo ThinkPad X220t (4299-2QG) [1]: clonezilla-2.0.1-5-amd64, booted from a usb-stick ------------------------------------------------------------------------------ Master SQL Server Development, Administration, T-SQL, SSAS, SSIS, SSRS and more.
