Argh, I missed it (I don't really like gmame's archiving... I will need
to get used to it).

I have the same :


Apr 29 22:42:41 favia kernel: [   72.272045] ehci_hcd 0000:07:01.2: force halt; handhake ffffc20000666814 00004000 00000000 -> -110


then


Apr 29 22:43:02 favia kernel: [   92.900094] mt2060 I2C write failed
Apr 29 22:43:02 favia kernel: [   92.905830] mt2060 I2C write failed (len=2)

Apr 29 22:43:02 favia kernel: [   92.944552] mt2060 I2C read failed
...............

and at one point I get the following before I shut down


Apr 29 22:44:27 favia kernel: [  177.818215] dvb-usb: could not submit URB no. 0 - get them all back
Apr 29 22:44:27 favia kernel: [  177.818222] dvb-usb: error while enabling fifo.

I'm with that too. I was just really busy at the time to dig into it.

I saw that one too, it arrived as I subscribed to the proper list.

I'm not directly concerned now, but I will be facing this too when I
will want to upgrade my system to the current Ubuntu release.


Soooooo...

What can I/we do to help track/fix this?

I'm game for a bit of testing, within reason, though, at the system is
in production.

Do you know if the issue is the same with a Nova-TD stick? If it is,
then I could be able to use debugging as an excuse to buy one, and then
add 2 tuners to the system when all is done :o)
