Subject: Lenovo Ideapad 5 Pro-16ACH6 Laptop Updated GSCN33WW BIOS Slows Linux

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.

If there is anything I can to do help identify/fix the problem, please let me 
know.
