The crash that occurred at bootup didn't get logged.  I'm not sure if
I checked dmesg.  Do you think if I replicated the crash, then
rebooted with the working kernel, that the information from the crash
would still be in dmesg?  Where would it be stored?  The crash happens
immediately when the kernel is loaded, before any of the filesystems
are brought up.  The trace information is the first thing that's
displayed.

Here is a photo of what is displayed on the screen:

The kernel messages from running "modprobe i915" did get logged:
