Only works when adb is enabled

[dstahlke]

I am running CyanogenMod 7 on an HTC G2. When adb over USB is enabled in Settings/Applications/Development, superuser works just fine. However, when adb is disabled there is trouble.

When Root Explorer is run, I get the popup "Root Explorer has been granted superuser permissions" but then after a couple of seconds I get "Root Explorer hos not yet managed to get root access" and the app exits.

From Android Terminal, when I run su (actually, I set the shell to be "/system/xbin/su root -c bash") the command just hangs until I press ctrl-C. After pressing ctrl-C, I am dropped to the root shell. Running "ps fauxww" from Debian chroot, I see that su is apparently stuck when running "am broadcast". I'll attach the logs and ps results.

logcat output when running /system/xbin/su and then hitting ctrl-C:
