the line
ck804xrom ck804xrom_init_one(): Unable to register resource
is mentioned in
https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/90863 as
possible just a warning.
however as also stated in the above mentioned bug report the line
resource map sanity check conflict:
possible signals a bug in the kernel. I dont know if the patch from
http://linux.derkeiler.com/Mailing-Lists/Kernel/2008-10/msg08462.html is
allready in the ubuntu version of the linux kernel and since I couldnt find a
bug report regarding the second line I opened this one.
also the computer showed signes of unusual high load and was completly
unresponsiv. I had to restart the maschine to get it back to a usable state.
my uname -a
