Now the problem occured in the middle of watching an FTA channel while
recording a CA channel.  The picture froze and changing to another FTA channel
just produced the regular garbage.  The syslog says:

Jul  5 00:04:07 vdr kernel: av71101: ARM crashed!
Jul  5 00:04:08 vdr kernel: av7110_fw_cmd error
Jul  5 00:04:08 vdr last message repeated 3 times

Jul 5 00:04:24 vdr vdr[8120]: receiver on device 2 thread ended (pid=8120,
tid=622603)
Jul 5 00:04:24 vdr vdr[5088]: cTS2PES got 3561 TS errors, 1200 TS continuity
errors
Jul 5 00:04:24 vdr vdr[5088]: cTS2PES got 276 TS errors, 189 TS continuity
errors

The CA channel I'm recording (32) still shows fine.
