You could use either netconsole or blockconsole. Netconsole requires a second machine to capture the information, blockconsole requires a usb key or something similar to write to. In both cases you will get the entire console output in a file, often including very helpful messages leading up to the crash.
Blockconsole currently lives here: https://git.kernel.org/cgit/linux/kernel/git/joern/bcon2.git/
