Idle power of kernel 6.0.1-1.1 is 35 Watt. Previous kernels have 18 Watt. Blacklisting thinkpad_acpi results in normal idle power of 18 Watt of kernel 6.0.1-1.1. The original report in openSUSE bugzilla: https://bugzilla.opensuse.org/show_bug.cgi?id=1203404 Karl, which kernel version did *not* exhibit the behavior? 5.19.x kernel worked fine, and 6.0.x started showing the problem? Also provide the more hardware details and dmesg outputs from both working and non-working cases. Created attachment 303034 [details]

I meant rather the case with the older good-working kernel (and thinkpad_acpi loaded). And, give the full dmesg outputs. Created attachment 303037 [details]

You need to identify which is the last working kernel version. Not that old openSUSE/SLE kernel. That said, check 5.19.y, 5.18.y, etc, to figure out which kernel started regression. |
