and I just noticed that the kernel panic message is not the same so it might not be related :

a second user reported the Kernel panic - not syncing: VFS: Unable to
mount root fs on unknown-block(0,0) error so I opened another ticket (Bug #17320)
#6 Updated by goupille 2019-12-09 16:20:49
we received another report for this kernel panic, on a MacBook Pro 2019

Indeed, this looks like a different problem than Bug #17320, because Bug #17320 does not affect 4.0 (while this one does), and this problem affects pristine Debian, while Bug #17320 is Tails-specific.
Please ask the affected users to trying the following sets of boot options in syslinux:
noapic
noapic efi=noruntime
noapic efi=old_map
noapic efi=nochunk
noefi
Note (mostly to myself): the kernel error happens in the get_cert_list
function from security/integrity/platform_certs/load_uefi.c
, which reads extracts a list of certificates from an EFI variable. I’m a bit surprised this code path is triggered at all on a system that does not support Secure Boot.
