>Description:
When running FreeBSD 6.2-BETA3 or 6.1-RELEASE in a VMware session with encrypted root filesystem, the geli password prompt does not work when the root fs is mounted at boot time. I put kern.geom.eli.visible_passphrase=1 into /boot/loader.conf to see what's wrong, result: the keyboard doesn't work at all. When kbdmux is deactivated by putting hint.kbdmux.0.disabled="1" into /boot/device.hints, the behaviour changes: Keyboard partly works, but about 90% of all keystrokes are lost. The problem only seems to occur when mounting encrypted volumes at boot time. Other people on the mailing list report similar problems running FreeBSD on real hardware.

>How-To-Repeat:
- Install 6.2-BETA3 or 6.1-RELEASE with encrypted root fs in VMware player 
- Put kern.geom.eli.visible_passphrase=1 into /boot/loader.conf
- Also try to put hint.kbdmux.0.disabled="1" into /boot/device.hints
