thanks for the detailed explanation.

Upgrading to a 64-bit kernel with a 32-bit userspace is the mid-term plan 
which might turn into a short term plan given the occasional hiccup
with PAE / low memory pressure.

Something tells me there might be issues with mISDN using a 64-bit kernel 
with a 32-bit userspace since ISDN is a feature that's not used much 
nowadays either. But that should be more or less easy to solve.

-> I consider the issue "fixed" from my side.

Cheers,
Thomas
