Does enabling the keyboard backlight (if available) and NumLock still work? What about pressing Alt+PrtSc+b? Can you try installing kernels packaged by Debian from between Debian 12 and Debian 13 from https://snapshot.debian.org/ to find the newest kernel that still works and the oldest broken one? > My solution now is to use a kernel from Debian 12.

These are 2 very different devices: Intel vs AMD CPU, Insyde vs AMI BIOS, like 6 years or so in between? So no I have no idea what could break both at the same time that is device(s) specific.

Hi Uwe, Hi Werner, thank you. > When you say the kernel freeze, does the machine still respond to pings? > Does enabling the keyboard backlight (if available) and NumLock still > work? What about pressing Alt+PrtSc+b? I have installed a more recent kernel again (6.17.8+deb13-amd64) and am now waiting for the next freeze. Then I can tell you more. > Can you try installing kernels packaged by Debian from between Debian 12 > and Debian 13 fromhttps://snapshot.debian.org/ to find the newest > kernel that still works and the oldest broken one? That could take a long time, even with binary search. The error only occurs sporadically. Best regards, Steffen

Hi Uwe, Yesterday there were no freezes. Today I had the first one after about 3 hours. > When you say the kernel freeze, does the machine still respond to pings? After the freeze, the laptop was no longer visible in web interface of the router. > Does enabling the keyboard backlight (if available) and NumLock still work? The backlight could still be turned on and off. I don't have NumLock. > What about pressing Alt+PrtSc+b? It didn't work anymore. kernel: 6.17.8+deb13-amd64 Best regards, Steffen

Hi, > Can you try installing kernels packaged by Debian from between Debian 12 > and Debian 13 fromhttps://snapshot.debian.org/ to find the newest > kernel that still works and the oldest broken one? I have tested several kernels. Kernel 6.6.8 does not boot. Kernel 6.8.11 starts up, but has the freeze bug. The same applies to kernel 6.12.6. It can sometimes take up two days or more for the first freeze to occur. There is no apparent cause; it seems to be completely random. Kernel 6.1.0-35-amd64, however, runs absolutely stable. Best regards, Steffen
