Hello,
We have one fedora setup with fedora 6.5.6-300.fc39.x86_64 kernel that works perfectly with our driver and application.
When we tried duplicate on another system with same kernel, same cpu hw the only difference it has newer bios application crushes. Bellow dump from dmesg generated when it crushes.
How we can debug this problem? I am not able find any where documentation on how install and use debug version for the kernel.
Any help apriciated.
Thanks,
