i had same issue when i moved from mythbuntu to arch and at the time
had a later kernel. this issue may be fixed in more recent kernels. but
at the time i put the following into a .conf file in /etc/modprobe.d to
disable the offending modules and all was well after. i used theses
lines:

blacklist lirc_zilog
install rc_core /bin/false
install rc_hauppauge /bin/false

i called file hdpvr.conf

i control hdpvr via firewire so i did not need any modules. i hope this
helps.
