I have the same issue with -71
If I hit CTRL-ALT-DEL after the error and then hit enter it boots.
Waiting for the 30sec timeout also works.

No AMD iGPU / APU in this system.
However my System76 Kudu6 laptop with Ryzen 9 5900HX, Radeon RX Vega 8
APU boots -71 just fine on the first try, no issue at all.

Title:
Kernel 5.15.0-71 fails to boot on Ubuntu 22.04 (possibly specific to
Ryzen APUs)
Status in linux package in Ubuntu:
Confirmed
Bug description:
Since upgrading to 5.15.0-71 a couple of days ago, my PC sporadically
fails to boot. I see the following error messages:
"error: cannot allocate kernel buffer
error: you need to load the kernel first.
Press any key to continue..._ "
I am then returned to the GRUB boot menu.
This has also been experienced by two other AskUbuntu users:
https://askubuntu.com/questions/1465460/after-kernel-update-error-
cannot-allocate-kernel-buffer-you-need-to-load-kern . The common theme
appears to be Ryzen APUs; two of us have 3400Gs and one has a 7600.
In my case, the issue appears to be more likely to occur when I have
to force-reboot because the system is frozen (due to a separate bug
which I will link when I can find it again). But I have not yet
reproduced it.
Also the log files attached to this report may not contain relevant
information as the last couple of boots worked correctly. I will try
to capture a relevant kernel log now that I know this is a kernel
issue.
