The patch by Jose Alberto Reguero <jareguero@telefonica.net> seems to cure the USB disconnects which often results in a kernel Oops. I used the one which only corrects the behaviour for the Nova-T 500 since that is that is the hardware I have (and he said the other patch was untested). The one I used is this: http://www.linuxtv.org/pipermail/linux-dvb/2007-July/019209.html He also had one that patches for all dibcom devices, though that one is untested). Reproducible: Sometimes Steps to Reproduce: For more info search for Nova-T 500 or USB disconnects on the linux-dvb mailing list.
Created attachment 126116 [details, diff] This patch fixes Hauppauge Nova-T 500 USB disconnects.
This patch hasn't made it upstream yet and looks like it's still under discussion. Will keep an eye on it.
Just a FYI, the linuxtv WIKI has been updated with a different/newer version of the patch and a few other patches http://linuxtv.org/wiki/index.php/WinTV-NOVA-T-500_PCI
I have had 1 USB disconnect since applying those patches. So not 100%. Updated page: http://linuxtv.org/wiki/index.php/Hauppauge_WinTV-NOVA-T-500
Any news here? Looks like this patch still hasn't made it into mainline?
They (dvb-v4l) are trying new firmwares as well, however at the moment I am waiting for it to be more stable. I am still using the patch above, which is ok, but not 100%, I have also had some issues with recordings producing empty or near empty files (with a small purple block in the corner). I think it could be sasc-ng not being able to decrypt because there might be tuning problems (not often and mostly on channels I don't use a lot). Despite using the options dvb_usb_dib0700 force_lna_activation=1 trick (maybe I should try it off, long time ago I set it). and they changed the wiki address again... http://www.linuxtv.org/wiki/index.php/Hauppauge_WinTV-NOVA-T-500
So the firmware is supposed to solve this problem rather than a kernel patch? The disconnect patch was removed from the wiki as of this edit: http://www.linuxtv.org/wiki/index.php?title=Hauppauge_WinTV-NOVA-T-500&diff=10617&oldid=10616 However the patch referenced is not merged into any of the dvb trees that I can see.
I run off gentoo-sources/2.6.22-gentoo-r5 tree, so the patch is for that. I have not tried the firmware together with 2.6.22 to see if I can dispense with the above patch. Might be possible but Patrick Boettcher wants people to use v4l-dvb source. "> - Will it require the latest v4l-dvb source ?? Yes it is better." The answer is a bit ambiguous...
any chance you could save me a bit of time and write to their mailing list asking about the correct solution of this problem?
OK, the wiki has been updated with this link: http://www.linuxtv.org/pipermail/linux-dvb/2007-September/020348.html Please try that firmware.
According to the list still some reports that it happens with the new firmware, personally I was a bit worried, since there was one report that said that mythtv failed to tune to a channel after a day, someone else said that mythtv does that. But I guess I really should try the new firmware, on a stock gentoo kernel, except Edit /usr/src/linux/drivers/media/dvb/dvb-usb/dib0700_devices.c Change the line .firmware = "dvb-usb-dib0700-01.fw", \ to .firmware = "dvb-usb-dib0700-1.10.fw", \
ok, 1 day using new firmware and "stock" gentoo-sources-2.6.22-r5, so far so good. I am not using the IR remote receiver.
David, So are things still working ok, now?
Well, haven't had any USB disconnects as of yet...
I'm going to close this. Please re-open if you feel you are still having any of the same symptoms.
