I am using the current FC5 kernel, 2.6.17-1.2187_FC5, and last built v4l-dvb from the mercurial source at linuxtv.org earlier this week (24 Sept 2006).
Both receivers initially work fine in MythTV, except the PCI receiver is not able to receive the SBS channel here in Melbourne, Australia. SBS works fine on the USB receiver. (To get SBS and channel Nine to work at all, I had to add the +166667Hz offset to the channel frequency, as per http://www.linuxtv.org/pipermail/linux-dvb/2006-July/011623.html.)
It seemed like a signal strength problem with the SBS channel, as lock can be slow and frame updates are delayed/pixelated/corrupt. However, I tried the card/antenna in a WinXP machine and all channels are received perfectly. The Windows receiver app shows the signal strength is 100% for all channels:
ABC - 100% (29.1dB)
Seven - 100% (30.1dB)
Nine - 100% (30.6dB)
Ten - 100% (29.0dB)
SBS - 100% (25.3dB)
After working ok initially for anywhere up to a day or so (except for SBS on PCI), the second problem happens. The USB receiver suddenly stops working and syslog is flooded with "bulk message failed" messages:
dvb-usb: recv bulk message failed: -71
dvb-usb: bulk message failed: -32 (1/0)
last message repeated 14 times
dvb-usb: bulk message failed: -32 (1/0)
last message repeated 19 times
dvb-usb: bulk message failed: -32 (1/0)
last message repeated 20 times
...
If I just reboot, the /dev/dvb/adapter1/* devices are missing. The only way I can get it working again is by shutting down the system, and pulling the power before restarting, so the firmware for the USB receiver is reloaded.
Would much appreciate any advice on how to get some stability back with the new card's USB receiver and on the SBS channel reception for the PCI receiver.
Thanks in advance,
Mark.
