system boot freeze while typing crypt password

[Joe Barnett]

Rebooted my system and at the luks/crypt password entry screen, I was able to type about half my password when the system locked up and became unresponsive. Hard poweroff was the only thing that worked. Same problem in recovery mode at the text prompt for the crypt password. saw the same behavior after multiple reboots with both 6.5.0-10 and 6.5.0-9 kernels.

Eventually was able to boot successfully by waiting a while before typing the password, and typing it very slowly. no idea what triggered the succesful password entry though, or how to even debug the system when its in this state
