to read DVB device
Product: kaffeine
Version: 2.0.17
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR

P14f1888000706a18: LG Electronics LGDT3306A VSB/QAM Frontend
STEPS TO REPRODUCE
1. Upgraded linux kernel to latest archlinux kernel 5.17.1 kaffeine fails to
play/scan the channels.
ran this:
pacman -Syu
2. Downgrade to linux kernel 2022/03/15 kernel 5.16.4 Kaffeine works
perfectly.
Using this mirror, by setting /etc/pacman.d/mirrorlist to contain:
http://archive.archlinux.org/repos/2022/03/15/core/os/x86_64/
and running
pacman -Syyuud
OBSERVED RESULT
Slightly old kernel from March 2022 works and the newest April 2022 kernel
fails to run Kaffeine.
Diagnostics menu inside kaffeine says: ioctl FE_READ_STATUS failed for
frontend /dev/dvb/adapter2/frontend0
EXPECTED RESULT
Easy linux upgrade, nothing special, should have worked. Kaffeine was not
upgraded.
It is the January 2022 Kaffeine version 2.0.18 in all cases.
SOFTWARE/OS VERSIONS
Archlinux kernel 5.17.1 April 10, 2022 Kaffeine fails.
