Approximately 20% of devices are experiencing intermittent boot failures
with this kernel version. The issue appears to be related to auto login
failures, where an incorrect password is being detected on the serial
console during the login process.

We are investigating this problem.

Test environments:
 - dragonboard-410c
 - dragonboard-845c
 - e850-96
 - juno-r2
 - rk3399-rock-pi-4b
 - x86

Regression Analysis:
- New regression? Yes
- Reproducibility? 20% only

Test regression: 6.15.5-rc2 auto login failed Login incorrect
