Kernel 6.6.26-1 cause system freezes & Kernel bug errors

Hi,

I recently installed Kernel 6.6.26-1 and I am facing a problem that after some time working with the system the system freezes and nothing can be done and I just have to press the power button to turn off the system.(I can only move the mouse but nothing can be done with it and the keyboard doesn’t work at all)

Logs:

journalctl -b -1 -p3

I had this problem almost every day in the last few days, and the first time I encountered this problem, I saved the log and placed it in the section below.

Meanwhile, a solution came to my mind is to go back to the previous kernel (6.1.85-1).

Although in it (Kernel 6.1.85-1) I was facing another problem in the way that when I wanted to suspend the system, sometimes it worked, but sometimes after pressing the Suspend button, the screen went black, but the cpu was still working, and the keyboard and the mouse didn’t work either. It seems that it was not completely suspended and the system could not be used and I had to turn off the system with the power button.

If anyone has got any idea what is happening, please don’t hesitate to tell

Thank you
