I have tried two new kernel versions fromwww.kernel.org site, the Kernel 6.10.5 and 6.1.105. > Additionally, I have used Debian at least since kernel version 6.1.22. All kernels present warnings in the same file with slightly different outputs in dmesg. I am compiling the kernel with the config-6.1.105 file in the attachment. Unless Imre has some obvious ideas what the problem is, please file the bug report at freedesktop.org gitlab as described in [1]. While the detail in your report here is great, I'm afraid it's just going to be completely forgotten on the mailing list. Thanks, Jani.
