Finding all the command-line console settings can be a challenge. I had
thought it was supposed to be "console=hvc0 earlycon=hvc0".
With that though I finally have some output which claims to come from the
Linux kernel (yay! finally hit this point!). As we were both guessing,
very early kernel panic:
[ 0.000000] efi: Getting EFI parameters from FDT:
[ 0.000000] efi: Can't find 'System Table' in device tree!
[ 0.000000] cma: Failed to reserve 64 MiB
[ 0.000000] Kernel panic - not syncing: Failed to allocate page table page
I don't know whether this is a problem with the mini-DT which was passed
in versus ACPI tables. I note a complete lack of ACPI table information.
The kernel is from a 5.6-based kernel tree. I'm unsure which portion to
try updating next.
