Motorola has acknowledged the complaints of a number of DROID X owners who have upgraded to Android 2.2 and are experiencing "issues" related to the update. Some of the issues are minor, but a couple (failure to boot, kernel panic) are definitely not. Motorola is saying the bugs have been squashed, but the fixes will be incorporated into a yet-to-be-announced "future software release." Here's what a Moto employee on the DROID X support forum had to say:
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.
