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
