Hi all,
On my arm64 Huawei D06 dev board, I see this on sometimes on linux-next
20200310 just as the boot completes:

The system is still alive, as keypresses respond with garbage.
Full dmesg:

v5.6-rc4 is ok from my attempts.
Anyone else see such an issue?
Thanks,

FWIW, that looks every bit like something changing the UART baud rate
under the console's feet, either explicitly, or implicitly by messing
with the input clock behind the driver's back.

Maybe, but I didn't think that the kernel would know about the UART
clock for ACPI-based FW.
Anyway, today's linux-next does not seem to have the issue from my
limited testing. I'll keep an eye out.
Cheers,
John
