Hi,<br><br>tried all those various suggestions, but it still doesn't change anything for me :-(<br><br>Switching from DVB-T to DVB-S locks up the frontend.<br><br>Investigation shows that the frontend appears to lockup because, actually, it's the backend which crashes and restarts.<br>
<br>Backend log shows<br><br>*** glibc detected *** /usr/bin/mythbackend: munmap_chunk(): invalid pointer: 0xb5cb3020 ***<br><br>(or similar)<br><br>followed by a restart. This on attempting to start the DVB-S channel.<br>
<br>Ring any bells with anyone?<br><br>Ta<br>liam<br><br><br><div class="gmail_quote">On Wed, Aug 25, 2010 at 3:21 PM, Liam Friel <span dir="ltr"><<a href="mailto:liam.friel@gmail.com">liam.friel@gmail.com</a>></span> wrote:<br>

ubuntu 9:10, myth 0.22, <font style="font-size: 10pt;" color="black" face="Verdana,Arial,Helvetica" size="2"><font style="font-size: 10pt;" color="black" face="Verdana,Arial,Helvetica" size="2">v4l-dvb-20091103 drivers, </font></font><font style="font-size: 10pt;" color="black" face="Verdana,Arial,Helvetica" size="2"><font style="font-size: 10pt;" color="black" face="Verdana,Arial,Helvetica" size="2">1.22.82.0 firmware, and </font></font><font style="font-size: 10pt;" color="black" face="Verdana,Arial,Helvetica" size="2"><font style="font-size: 10pt;" color="black" face="Verdana,Arial,Helvetica" size="2">2.6.31-14 kernel.<br>
Front end used to freeze occasionally (going to black and white, which I also posted here about), but would always return working 20-30 seconds later.<br>It was around the time I upgraded to 2.6.32 kernel that I lost my EIT data, but this might have been coincidence.<br>
It was never really right after this, and since upgrading to 10.04 it's gone from bad to worse!<br></font></font>                                            </div>
