Yes, these two logs are from the same kernel.

I have not seen that problem before, but certainly is an unrelated problem: the
bug still happens when booting with modprobe.blacklist=rtl8723be, as you
suggested, and when it happens that soft lockup is not always present.

Also, another piece of information: when the problem does not happen, I see one
console message right before the plymouth bootsplash takes over, and it is
timestamped 2.xxx seconds. When it does happen I don't even see that message,
not the plymouth splash or anything else until X is reached and I move the
cursor or press any key. So my uninformed guess would be that the problem is
related to something that happens during the first 3s of the boot process.

Sorry for the noise, I'm attaching a 2nd log from the same kernel where the
problem happens in which the lockup does not happen. Please let me know if
there is something else I can provide or check to help fight this regression. I
can provide a video of the problem happening and the expected results if that
is of any help.
