This breaks ARC booting (no output on console).Could you provide the kernel boot arguments that you use? This series is partly about addressing users that have used boot arguments that are technically incorrect (even if had worked). Seeing the boot arguments of users that are not experiencing problems may help to reveal some of the unusual console usages until now.
Kernel command line: earlycon=uart8250,mmio32,0xf0005000,115200n8 console=ttyS0,115200n8 debug print-fatal-signals=1 And we do have serial driver built-in. Thx, -Vineet
