I use two different Gmail accounts on my Droid. When I try to add the second account I get a partial reboot. The phone reboots to the boot animation screen - not all the way to the white M logo.
I will reload this after another wipe and try a second time to load two Gmail accounts.
I also have two Gmail accounts and for the record I did not have any issue. I realize this doesn't help much, but I just wanted put it out there that it's not a universal issue with the ROM.
I am having the partial reboot issue, just noticed it. I use 5(!) gmail accounts and trying to add the 2nd one this problem came up. Going to try a few tricks up to reflashing.
EDIT: Just cleared the application data / cache, next cleared data / cache from clockwork, then reflashed the rom, then tried a old gmail2.3.zip (update.zip) file I had laying on my sdcard.
Nothing works, I have tried with Wifi on and off, 3g data on and off. The min you hit add account from gmail / menu / accounts / add account
the phone software reboots (does not display a M logo, starts right on the bootscreen).
EDITAGAIN: I tried flashing the MIUI V5 Modded & Themed over this ROM, and installed Gmail from the market. Same problem, softreboots at add account.
