I am using 21-fixes on F8 and I see:
Top causes for wakeups:
54.5% (337.4) mythbackend : do_nanosleep (hrtimer_wakeup)
15.0% ( 92.8) kdvb-ca-0:0 : schedule_timeout (process_timeout)
13.0% ( 80.2) <interrupt> : saa7146 (0), via at pci:0000:01:00.0
9.4% ( 58.4) mythbackend : schedule_timeout (process_timeout)
2.5% ( 15.4) mythbackend : futex_wait (hrtimer_wakeup)
1.9% ( 12.0) <kernel module> : usb_hcd_poll_rh_status (rh_timer_func)
[root at recorder ~]# mythfrontend --version
Please include all output in bug reports.
MythTV Version : exported
MythTV Branch : branches/release-0-21-fixes
Library API : 0.21.20080304-1
Network Protocol : 40
Options compiled in:
linux release using_oss using_alsa using_backend using_dbox2 using_dvb
using_firewire using_frontend using_hdhomerun using_iptv using_ivtv
using_joystick_menu using_lirc using_opengl_vsync using_v4l using_x11
using_xrandr using_xv using_xvmc using_xvmcw using_xvmc_vld
using_bindings_perl using_bindings_python using_opengl
using_ffmpeg_threads using_libavc_5_3 using_live
So what's the status? This is 'normal'?
There's only one multiplex, one real tuner here.
Using the virtual tuners I record three channels.
