https://bugzilla.kernel.org/show_bug.cgi?id=210457 cfr (reescf@xxxxxxxxx) changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |reescf@xxxxxxxxx --- Comment #1 from cfr (reescf@xxxxxxxxx) --- Lenovo ThinkPad X720 is also affected by this, but it is not sporadic, as far as I can tell. Not once since installing my current kernel have I seen normal behaviour following sleep. The problem persists if the machine is rebooted. Only powering off and restarting restores the expected behaviour. The bug seems to be a regression. See https://bugzilla.kernel.org/show_bug.cgi?id=196129. My machine was not affected by the original bug, but the problem looks to be the same. Following sleep: cat /sys/devices/platform/thinkpad_hwmon/hwmon/hwmon7/temp* 0 1000 0 0 0 0 0 cat: /sys/devices/platform/thinkpad_hwmon/hwmon/hwmon7/temp1_input: No such device or address cat: /sys/devices/platform/thinkpad_hwmon/hwmon/hwmon7/temp2_input: No such device or address 0 0 0 0 0 0 0 and cat /proc/acpi/ibm/thermal temperatures: -128 -128 0 0 0 0 0 0 0 0 1 0 0 0 0 0 Prior to sleep, only the second sensor is missing and acpitz-acpi-0 gives a sane reading. Following, the first goes AWOL and acpitz-acpi-0 is stuck at 48. Removing and reloading thinkpad_acpi makes no difference and, for me, re-sleeping and rewaking makes no difference either. -- You may reply to this email to add a comment.
