Steps to Reproduce: 1. Reboot laptop (Lenovo Yoga S1 (20CD0038MS)) 2. Check dmesg Actual results: ACPI errors in dmesg Expected results: No ACPI errors in dmesg Additional info: I don't know if this causes any issues. Just reporting this issue because it's tagged as error dmesg.

These errors are almost always caused by questionable ACPI tables. The message are harmless, if annoying. Can you share the output of dmidecode? It would also be good to see if there is a bios update
Thanks for checking this. BIOS is the latest, unfortunately. I will post output of dmidecode this weekend as I gain access back to my laptop.

(In reply to Otto Koskela from comment #6) > Created attachment 1470329 [details] > dmidecode fedora 28 It also happens with my Lenovo Yoga S1 but running Ubuntu. Seems it is cross-distribution problem. Anyway, I didn't observe any bad behaviour other than dmesg messages.

this keeps spamming my email, what to do?
As far as I know, this is the same issue as on https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=201678 ie ThinkPad S440. That is ECOR EmbeddedControl OperationRegion per the ACPI specification is 0xFF maximum range, but Lenovo uses 0x800 with a block at offset 0x668 including the thermal registers: Offset (0xF8), TSHT, 8, TSLT, 8, PENV, 8, PLMX, 8, CFAN, 1, Offset (0x668), CPU1, 8, GPU1, 8, TML0, 8, TMR0, 8, TMR1, 8 the Linux kernel does not support EC beyond 0xFF (and the operations on the EC are 8 bits so it would not be possible to access 0x668 without a rework of the kernel code. The result is the ACPI thermal is not working on Linux. I wonder if it works on Windows and if there is a way to check if it does (would be of interest to know if such an out-of-specification EC is supported by the Windows kernel). I still use my Thinkpad Yoga S1, so can test it (mine is also a 20CD model) As of now I tested moving this 0x668 offset block to 0x68 an offset and got an incorrect ACPI thermal value acpitz-acpi-0 Adapter: ACPI interface temp1: -273.2°C Will try offset 0x66, but I have a hard time believing Lenovo devs both use a wrong range (0x800) and a wrong Ofsset 0x668 by mistake. It might be on purpose but why... If anyone has a contact at Lenovo and could tell if it is a mistake (it is quite asy to fix the dsdt in Linux at the user level, even though I see no way for distribution to ship a fixed dsdt. Is there a way to dump the ec region on linux? sudo dmidecode [sudo] Mot de passe de prahal : # dmidecode 3.5 Getting SMBIOS data from sysfs. SMBIOS 2.7 present. 71 structures occupying 2680 bytes.

I found how to dump the ec on linux ("ec" tool in linux kernel source repository tools/power/acpi, make then "sudo ./ec -r", gives: 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 00: 26 85 a0 46 00 86 05 00 00 08 00 00 0e 00 00 00 10: 00 00 ff ff d0 0c 00 00 4b ff 00 00 ff ff 1d 00 20: 00 00 00 01 d5 00 00 00 00 00 00 00 e1 00 00 00 30: 80 00 02 00 50 04 00 00 86 00 30 18 00 00 00 00 40: 00 00 00 00 00 00 10 00 d0 00 00 00 00 00 00 00 50: 00 90 02 0e 22 2a 39 3c 01 01 01 01 00 00 00 00 60: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 70: 00 00 00 00 04 00 00 00 00 00 00 00 00 00 00 00 80: 00 00 00 06 00 00 00 00 00 00 00 00 00 00 00 00 90: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 A0: bb 0e d6 0f ff ff 5d 00 00 00 92 3f ff ff c0 00 B0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 C0: 00 00 00 00 00 00 00 00 00 5a 00 00 00 8e 00 00 D0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 E0: 00 00 00 00 00 00 00 00 14 30 00 00 44 80 06 00 F0: 47 51 48 54 36 33 57 57 00 00 00 80 00 00 00 00 with sensors showing 47°C and: 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 00: 26 85 a0 46 00 86 05 00 00 08 00 00 0e 00 00 00 10: 00 00 ff ff d0 0c 00 00 4b ff 00 00 ff ff 1d 00 20: 00 00 00 01 d5 00 00 00 00 00 00 00 e1 00 00 00 30: 80 00 02 00 50 04 00 00 86 00 30 18 00 00 00 00 40: 00 00 00 00 00 00 10 00 d0 00 00 00 00 00 00 00 50: 00 90 02 0e 22 2a 39 3c 01 01 01 01 00 00 00 00 60: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 70: 00 00 00 00 04 00 00 00 00 00 00 00 00 00 00 00 80: 00 00 00 06 00 00 00 00 00 00 00 00 00 00 00 00 90: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 A0: bb 0e d6 0f ff ff 5d 00 00 00 92 3f ff ff c0 00 B0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 C0: 00 00 00 00 00 00 00 00 00 5a 00 00 01 50 00 00 D0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 E0: 00 00 00 00 00 00 00 00 14 30 00 00 44 80 06 00 F0: 47 51 48 54 36 33 57 57 00 00 00 80 00 00 00 00 with sensors showing 68°C fro the cpu: coretemp-isa-0000 Adapter: ISA adapter Package id 0: +68.0°C (high = +100.0°C, crit = +100.0°C) Core 0: +64.0°C (high = +100.0°C, crit = +100.0°C) Core 1: +68.0°C (high = +100.0°C, crit = +100.0°C) note the offset 0x668 has a CPU1 field in ECOR that is read by method _TMP of Device TZ01: Method (_TMP, 0, Serialized) // _TMP: Temperature { Local0 = \_SB.PCI0.LPCB.EC0.CPU1 Return (Local0) } but out of 0xCC and 0xCD fields I see no difference (sometimes the 0xAA field changes from 0x92 to 0x93 but that would not account for the temperature readings). And these are already defined in ECOR as: Offset (0xCC), PWMH, 8, PWML, 8, itself read by method PWMG in scope HKEY of Device EC0. So I can only guess that Lenovo devs purposedly used an offset out of range to disable thermal ACPI the dirty and fast way. If anyone has a contact in Lenovo, that would help.
