[Bug 69555] Re: Backspace fired every 5-10 seconds without pressing any key by saa7134 module

Fri May 14 19:06:57 UTC 2010

Hello,

Same problem in Feisty 7.04 with a Pinnacle TV pci board...
A "&" was generate every 5 second... or a random caracter every 5 seconds...

I finaly remove the TV board, and the problem disapear.

No, I use an other PC, and Ubuntu 10.04.
I think that probably bug was resolved ?

I put again, some week ago (in 10.04 RC) the Pinnacle board to make some Digital TV test (the Pinnacle board is DVB-T compatible I think).
No problem at this moment (except that I don't succeed my TV test)...
I leave the pci board inside my PC.

Today, I make some upgrade. I don't know exactly when this start again.
But it start again !
Not every 5 seconds, less... random... 1 caracter after 10 sec, or 1 min, or more...
But some time, when I type a text, I have a random letter, or the speaker go to "mute" alone, or a pop-up asking me if I want to stop, restart, pause the computer come on screen.

Borring !

I try several keyboard, ps2 or USB, but allways the problem : it's not a
keyboard problem.

Of course, I can remove the Pinnacle TV board :p
But I prefers first send you the documentation.

I don't yet find and install the Pinnacle firmware... 
but It must not "auto-generate" keys like this !
