FWIW,
I haven't tested my nanoStick T2 (model 290e) with anything else than
Kaffeine, but it has been running for many days, and I haven't seen
the problem you describe.
I'm using Xubuntu 11.10:
tingo@kg-f4:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 11.10
Release: 11.10
Codename: oneiric
tingo@kg-f4:~$ uname -a

and media drivers (from http://git.linuxtv.org/media_build.git) built
on 2012-02-08.
