Hi,
Please CC me with any response.
I updated my Ideapad 5 Pro 16ACH6 BIOS (AMD Ryzen 5800H) to GSCN33WW.
Performance under Linux dropped what seemed to be by a factor of 10. It was
painful to use the machine. I was using the latest 5.18.x kernels. I tried
various things including dropping back to previous kernel versions to no
avail. Finally I reverted to the previous BIOS verson GSCN32WW and the
performance returned.
Here is the summary of changes for GSCN33WW.
