>Description:
When GELI encrypted partitions are detected, GEOM tries to setup the parameters and asks for passphrase. There is a problem with the kernel output going on, while the system is waiting for input. On my system during this phase acd0(4) is detected and all input (the passphrase) becomes invalid.

Another problem is that the passphrase prompt is not the last kernel message, but mixed with the other output. It's sometimes difficult to see what's going on. This problem is rather of cosmetic nature.

>How-To-Repeat:
Initialize a GELI partition that uses a passphrase and restart the system.
>Fix:
A workaround is to wait for the last kernel message and THEN begin to type the password.
