Hi Dieter,
you can try the rfkill utility that can be found in driver:wireless
project for 11.2 [1]. This utility can turn the bt dongle off [2]. If
the rfkill works for you then you can create a "hook" to switch the bt
dongle off before suspend. Some hints can be found in the package
pm-utils. If you want, open a bug report, we can create and test new
"hook" together and add it to pm-utils.
