folks, my T520 unexpectedly crashed. Since it was second times in 1 week, I started to care and in the syslog I found the following: May 25 12:33:57 opahapaka kernel: [42311.015889] thinkpad_acpi: THERMAL ALERT: unknown thermal alarm received May 25 12:33:57 opahapaka kernel: [42311.015893] thinkpad_acpi: unhandled HKEY event 0x6000 May 25 12:33:57 opahapaka kernel: [42311.015895] thinkpad_acpi: please report the conditions when this event happened to ibm-acpi-devel@xxxxxxxxxxxxxxxxxxxxx May 25 12:34:01 opahapaka kernel: [42314.411447] thinkpad_acpi: THERMAL ALERT: unknown thermal alarm received May 25 12:34:01 opahapaka kernel: [42314.411451] thinkpad_acpi: unhandled HKEY event 0x6000 May 25 12:34:01 opahapaka kernel: [42314.411452] thinkpad_acpi: please report the conditions when this event happened to ibm-acpi-devel@xxxxxxxxxxxxxxxxxxxxx May 25 12:34:01 opahapaka kernel: [42315.097025] thinkpad_acpi: THERMAL ALERT: unknown thermal alarm received May 25 12:34:01 opahapaka kernel: [42315.097029] thinkpad_acpi: unhandled HKEY event 0x6000 May 25 12:34:01 opahapaka kernel: [42315.097030] thinkpad_acpi: please report the conditions when this event happened to ibm-acpi-devel@xxxxxxxxxxxxxxxxxxxxx May 25 12:34:02 opahapaka kernel: [42315.510725] thinkpad_acpi: THERMAL ALERT: unknown thermal alarm received May 25 12:34:02 opahapaka kernel: [42315.510728] thinkpad_acpi: unhandled HKEY event 0x6000 May 25 12:34:02 opahapaka kernel: [42315.510729] thinkpad_acpi: please report the conditions when this event happened to ibm-acpi-devel@xxxxxxxxxxxxxxxxxxxxx May 25 12:34:05 opahapaka kernel: [42318.654656] thinkpad_acpi: THERMAL ALERT: unknown thermal alarm received May 25 12:34:05 opahapaka kernel: [42318.654660] thinkpad_acpi: unhandled HKEY event 0x6000 May 25 12:34:05 opahapaka kernel: [42318.654661] thinkpad_acpi: please report the conditions when this event happened to ibm-acpi-devel@xxxxxxxxxxxxxxxxxxxxx May 25 12:34:05 opahapaka kernel: [42318.868549] thinkpad_acpi: THERMAL ALERT: unknown thermal alarm received May 25 12:34:05 opahapaka kernel: [42318.868552] thinkpad_acpi: unhandled HKEY event 0x6000 May 25 12:34:05 opahapaka kernel: [42318.868553] thinkpad_acpi: please report the conditions when this event happened to ibm-acpi-devel@xxxxxxxxxxxxxxxxxxxxx May 25 12:34:06 opahapaka kernel: [42319.702025] thinkpad_acpi: THERMAL ALERT: unknown thermal alarm received May 25 12:34:06 opahapaka kernel: [42319.702028] thinkpad_acpi: unhandled HKEY event 0x6000 May 25 12:34:06 opahapaka kernel: [42319.702029] thinkpad_acpi: please report the conditions when this event happened to ibm-acpi-devel@xxxxxxxxxxxxxxxxxxxxx May 25 12:34:07 opahapaka kernel: [42320.369630] thinkpad_acpi: THERMAL ALERT: unknown thermal alarm received So I did.
