Subject: Some SSDT tables are not loading with kernel >= 5.12
Date: Thu, 3 Jun 2021 19:26:59 +0200 [thread overview]
Message-ID: <f634a05a-e3a9-93ab-4b87-d41f5ee083a5@redhat.com> (raw)
Hi Rafael,
I've been helping some users with trying to get to the bottom of some
new ACPI errors with kernel 5.12, see:
https://bugzilla.kernel.org/show_bug.cgi?id=213023
After looking at dmesg output; and after editing the dmesg output
a bit so that I could do diff -u on it, the following stands out:
--- dmesg_5.10.38-1-lts 2021-06-03 16:29:41.372922210 +0200

Note how for some reason the kernel is no longer loading the Cpu0Hwp and
HwpLvt SSDT-s ?
Do you have any ideas what might be causing this ?
Regards,
Hans
