Bug#1048892: linux-image-amd64: 7z mistaken cpu core count, qemu vm's cpu are 50% slower than 5.10 kernel from debian 11
Package: linux-image-amd64
Version: 6.1.38-4
Severity: normal

Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate ***
* What led up to the situation?
After upgrade or reinstall from cd image to Debian 12 or 12.1
* What exactly did you do (or not do) that was effective (or
ineffective)?
After upgrade from Debian 11 to 12, qemu vm's cpu get 50% slower and "7z b" give me 2 times of my cpu core count,
If I reboot debian 12 with kernel from Debian 11 (kernel 5.10), qemu vm's cpu speed are as fast as on Debian 11; doing "7z b", cpu core count is correct.
* What was the outcome of this action?
* What outcome did you expect instead?
