Comment 4 for bug 204857

I get the same behaviour on my HP nx6125 laptop with both a nova-t and nova-t diversity stick. Either attempting to scan for, or watch dvb channels results in the following:

 MT2060: successfully identified (IF1 = 1220)

This was with the latest mercurial build from v4l-dvb but this doesn't seem to fix things and displays the same as the stock kernel modules. There were some disconnects with previous ubuntu kernel versions (gutsy and previous) but not nearly as frequent as is now happening. Looks like it's probabably an upstream issue as I've read of several other sufferers even with vanilla kernels. Could be my usb chipset or something more generic, lspci is below. Please let me know if I can provide any further debug.
