Hi All,
I use the Nemo board with a PASemi PA6T CPU and some values of lscpu are wrong since the RC1 of kernel 6.0.
┌──(mintppc㉿mintppc)-[~]
└─$ lscpu
Architecture: ppc64
CPU op-mode(s): 32-bit, 64-bit

Core(s) per socket: 1
Socket(s): 1

One core with 2 threads is wrong. Two cores are correct. Each core has one thread.
Have you modified the detection of the CPU?
Thanks,
Christian

Just for info:
The values have been fine again since the RC7 of kernel 6.0.
