#8092: mythtv-setup hangs on ioctl when adding HVR-2250
-----------------------------------+----------------------------------------
Reporter: kpyle@… | Owner: ijr
Type: defect | Status: new
Priority: minor | Milestone: unknown
Component: MythTV - Mythtv-setup | Version: 0.22
Severity: medium | Mlocked: 0
-----------------------------------+----------------------------------------
When attempting to add a HVR-2250 via the "new capture card" option in
mythtv-setup, the program shows a blank screen and becomes unresponsive.
The HVR-2250 is working outside of mythtv and can tune and capture, as
confirmed with gnutv from the dvbtools package.
OS is gentoo 2.6.32.8:
% emerge --info | head -n 1
Portage 2.1.7.16 (default/linux/amd64/10.0, gcc-4.3.4, glibc-2.10.1-r1,
2.6.32.8 x86_64)
% emerge -pv mythtv
media-tv/mythtv-0.22_p23069 USE="dvb -alsa (-altivec) -autostart -css
-debug -directv -faad -fftw -ieee1394 -jack -lcd -lirc -mmx -perl
-pulseaudio -python -tiff -vdpau -xvmc"
strace shows that mythtv is blocked on an ioctl:
