Re: dvb_usb_vp7045 regression after upgrading from 2.6.39.4 to 3.1.1
Did a few more tests. The tuning problems with my USB DVB-t card also show with kernel 3.0.9 and 3.1.4. If I boot into 2.6.39.4 the card still works flawlessly as before. All the kernels tested were built with the same kernel .config (plus changes introduced by 'yes |make oldconfig'). So I'd say this regression is real. Is there anything else I can do to help diagnose the problem? Should this report go into kernel.org bugzilla? cheers, David David == David Kuehling dvdkh...@gmx.de writes: Hi, after upgrading from 2.6.39.4 to 3.1.1., my usb dvb-t receiver started having tuning problems.
