my system sometimes can not boot.
I have done dmesg of correct boot and dmesg of fail boot.
I did diff and the problem is here ( I guess) … but why it is not happening always?
[ 16.208708] BUG: unable to handle kernel NULL pointer dereference at 0000000000000200
I have radeon graphic and integrated intel graphic. Since I do not need the dedicated radeon I am turning it off by this “echo OFF > /sys/kernel/debug/vgaswitcheroo/switch”. ( Starting as service on boot - systemd )
Can someone help me?
