Hello,
I am facing oft the ir-keytable crash with an coredump and mostly I
need to reboot whole device to have remote working again.
Note that here it creates coredump on an device which i actually not
use. On the Tevii USB S650 IR (IR-receiver inside an USB DVB re) which
is recognised as the rc1.
Here is the coredump and also on an paste page [1] for better reading.
Someone have any suggestion to solve this issue?
