[smyrno <1471616@xxxxxxxxxxxxxxxxxx>]

I just updated my BIOS.  (Thanks for giving me the opportunity to tinker with my BIOS)
And there is no improvement : 
The card only works when I boot Windows and then restart to Ubuntu.
I don't know what to add, the update has been seamless and I see no change.

However, I had the same issue with this PCI device on my previous
computer. That was 5 years ago. (I'm not prompt to issuing bugs) So it
seems not to be specific to my configuration.

Here is the BIOS version and release date:
~$ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
1601   
06/26/2012

Thank you for your help

Title:
  DVB device initialisation issue

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Hi, 
  I have a PCI card to receive DVB television on my desktop computer.
  The card works, but only if I restart the computer from Windows.

  I believe that Windows initializes something that does not get erased when the computer restarts, 
  and Ubuntu does not initialize this when it boots.
  This initialization gets erased when Ubuntu goes to sleep too.

  Please let me know any command that I could run to see differences
  between the card's configuration when it works and when it doesn't.

  Here is my lspci -vvnn for this device:
  0b:02.0 Multimedia controller [0480]: Philips Semiconductors SAA7146 [1131:7146] (rev 01)
  	Subsystem: KNC One Device [1894:0030]
  	Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx-
  	Status: Cap- 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx-
  	Latency: 64 (3750ns min, 9500ns max)
  	Interrupt: pin A routed to IRQ 17
  	Region 0: Memory at f7fffc00 (32-bit, non-prefetchable) [size=512]
  	Kernel driver in use: budget_av

  
  I saw on the KNC ONE website that they have a driver for the card. 
  I don't know if it fixes my issue. 
  But since the card works in some cases with a fresh install of Ubuntu without this driver, it seems that its a bug worth being fixed, right?
