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.
Summary of changes ================== General Information: GSCN33WW: BIOS Notification: 1. Fixed 1) Fix Security level 2 fail issue. 2) 2. Add 1) NA 3. Modified 1)NA EC Notification: 1). N/A
If there is anything I can to do help identify/fix the problem, please let me know.
Thanks
