The reason of this problem is that in 5.8 the default amount of nr_uarts has been changed from 4 to 32. This is causing ttyS0 to be remapped to ttyS4, breaking the user-space.

The solution is to set back the number of UARTS to 4. I tried to boot the kernel adding 8250.nr_uarts=4 to the kernel boot parameters in GRUB and /dev/console is now working correctly.

I'll send a fix for this to restore the previous behavior by default in the kernel and avoid breaking the user-space.
