Matt, the Droid X forums manager inn the Motorola support forums, posted this blog article yesterday acknowledging some of the issues with the Droid X Froyo 2.2 release:

If you have already upgraded to 2.2 for Droid X, you have found some new capabilities. Unfortunately, some owners also found new issues.  Here are some of the known issues raised by forums members, with some information about each. It is not intended to be a complete list at this time -- there are many more fixes and improvements in the works. I’ll update this list as information becomes available.

• Stuck on Moto logo after reboot – this was tough on a few owners. Very sorry about that. A fix has been developed for this and should eliminate the problem. It will be distributed in a future software release. If you are still experiencing this issue, click here.

• Random rebooting – while there always seem to be new conditions that can cause an electronic device to panic, we do have improvements coming that address and eliminate identified panic states. They will be distributed in a future software release.

• Wi-Fi connection and stability – improvements in Wi-Fi have been developed, to address several problem areas. They will be distributed in a future software release.

• Battery Manager “force close” errors – under some circumstances, pressing the battery icon under Menu > Settings > Battery Manager results in a forced close error. A fix has been developed for this and should eliminate the problem. It will be distributed in a future software release.

• Media won’t play – includes “sorry the player does not support this type of audio file," custom ringtone stop working, video won’t play, etc., until after a reboot. We believe we have identified the cause of these errors. A fix has been developed for this and should eliminate the problem. It will be distributed in a future software release.

• Music files cutting off the final four seconds or so – a solution has been developed. It will be distributed in a future software release.

At this time I don't have information about when the next software update will be available -- when I have it, I'll share it here.
