When I updated my Linux kernel to 5.11 I had the bad surprise to end up with a blinking underscore on reboot. It had been many years since an update had broken my system like that. I fixed it rather easily by booting in rescue mode and downgrading the kernel. I had no time to investigate so I just added linux to IgnorePkg at the time, But I don’t use Arch to run old kernels so today I took the time to fix it “properly”.
