Could you give hwinfo output and the dmesg output from Leap 15.4 and/or TW kernels?

Also, please try to install Leap 15.3 kernel on top of Leap 15.4 system, and check whether the problem is gone with that or not. (For installing Leap 15.3 kernel, you might need to pass --force or whatever option to ignore the package dependency.)

@Mr. Takashi Iwai, short answer: problem ist NOT gone. Installed 5.3.18-57 kernel on top of current Leap-15.4 System. Behaviror same as before. However, there's a long answer, too. There's a stochastic element to all this. See, if you have, say, 12 sorties of a Leap-15.4 (or TW, for that) system, then 9x you shall find that 60�C idle temp problem, and 3x temps move to ~45�C while the fan level moves to zero. Even did experiments with Legacy Boot vs. UEFI Boot but could not find deviating behavior there, i.e., with Leap-15.4 or TW you shall find the erratic 60�C idle temp issue, with Leap-15.0 ... 15.3, live is good.

@Mr. Takashi Iwai, problem still NOT gone. Today, installed 5.3.18-150300.59.93-default kernel on top of current Leap-15.4 System. Behavior untenable as before.

"untenable as before" means the behavior just like with Leap 15.4 kernel? And Leap 15.3 live image works as expected? If so, you can verify the kernel on the live image and on your test system; if both are with the same kernel but show the different behavior, the cause is rather in the user-space, not the kernel itself. -- You are receiving this mail because: You are the assignee for the bug.

If I remember correctly the Life system is ext4. The SSD install is btrfs. You may try an ext4 install on SSD. -- You are receiving this mail because: You are the assignee for the bug.

...

I have a multi-bootable SSD with TW, Leap-15.4 (with 3 kernels to choose from) and Leap 15.3 systems on it. Leap 15.3 always goes to idle temp 45�C, Fan level 0, however, the TW and Leap-15.4 systems both show the 60�C idle temp issue. Installing 15.3 Kernels on a virginly installed Leap 15.4 system does not help with the 60�C idle temps. And remember you CAN see 45�C idle temps, fan level 0, too, on the latter systems, however, only erratically with a "mesasured" probabaility of ~ 25%. So, these are the current results. What do you make of them, what do you especially make of the stochastic behavior?

Did you try the SSD on an other ThinkPad? Given the shaky behaviour I would check whether it occurs on other hardware too.

Today, I tried with a different SSD (of exactly the same type) on a different ThinkPad W530 (same type, too) and got similar results, however not quite the same. Leap-15.4 neither on btrfs nor on ext4 would reach 45�C and the fan would never relax to level 0. So with Leap-15.4 there was always the 60�C idle temp issue. With Leap-15.3 there was a surprise, on this ThinkPad temperatures would cease to 45�C only in 50% in about 10 reboots, the other 50% temperatures would stay above 55�C near 60�C, fan would wander between level 1 and level 2, but never would cease to level 0. Here's a table showing the results of days of installations and runs. ## 60�C Idle Temperatures Issue on ThinkPad W530 --- Device (A) vs Device (B) Leap-15.3 vs Leap-15.4 SSD vs Live-System btrfs vs ext4 --- Thinkpad (A) -> Leap-15.4 -> SSD -> btrfs 60�C = 75% / 45�C = 25% Thinkpad (A) -> Leap-15.4 -> SSD -> ext4 60�C = 75% / 45�C = 25% Thinkpad (A) -> Leap-15.4 -> Live -> ext4 60�C = 0% / 45�C = 100% Thinkpad (A) -> Leap-15.3 -> SSD -> btrfs 60�C = 0% / 45�C = 100% Thinkpad (A) -> Leap-15.3 -> SSD -> ext4 N.E.

Blacklisting of thinkpad-acpi causes temperatures to return to normal values. With the current version idle power is 36 Watt. Upon blacklisting idle power goes down to 18 Watt, the same value as observed with the older kernels. -- You are receiving this mail because: You are the assignee for the bug.

Thanks for the information!

Is thinkpad_acpi a part of Leap / TW officially?

Yes, it is: https://github.com/torvalds/linux/blob/master/drivers/platform/x86/thinkpad_... -- You are receiving this mail because: You are the assignee for the bug.

Ah of course; sorry, I was confused as if it were about tlp stuff.

So this sounds like a regression in thinkpad_acpi driver. Could you try to open a report on the upstream bugzilla.kernel.org? Put me (tiwai@suse.de) to Cc there.

bugzilla.kernel.org says: If you did not compile your own kernel from scratch, you are probably in the wrong place. I used kernel-vanilla v 6.0.1-1.1. Will that be appropriate? -- You are receiving this mail because: You are the assignee for the bug.

Ignore the warning and just go ahead. You're testing with the latest upstream code, and I can help building a kernel from the distro side, so there is no problem.
