DeckLink Studio 4K issue

(Ubuntu 12.04.4 LTS - kernel 3.11.0-15 - x86_64 - Motherboard=ASRock IMB-180)

We have an DeckLink Studio 4K card which is intermittently not appearing to the system upon boot. Every 4-5th boot of the system results in the card not appearing in the 'lspci' list.

We have also added the pcie_aspm=off option to the kernel command line but this does not help with this issue.

Note the Blackmagic card entry near the end in the first lspci is missing in the last lspci. This happens intermittently upon boot.

In our testing where we are simply rebooting the server after each boot, the card disappears usually around the 4th or 5 attempt and then reappears on the subsequent reboot.

To add to the above, we also tried an DeckLink Duo card in the same server and had no issues at all (it always appeared and worked after many reboot tests).

I would suggest sending this to our support team via email so they can try and address this for you. you can find the contact info on the company tab of the website.

Many thanks. We have emailed the issue.

Was there a resolution to this issue?

I am encountering the same problem with a DeckLink SDI 4K card.

We were asked to try the card on another motherboard using Windows.

Unfortunately this is not straightforward for us as we are a Linux outfit with a smattering of MacBook Pro's, so no Windows PC's in sight! As soon as I come across a PC (with a suitable PCI-E slot) I will try this again as Blackmagic requested.

So far our customer is content to reboot the server until the card is recognised! Obviously I am not terribly happy with that situation!

PS: This issue was still present for us on the latest 10.1.1 drivers.

I'm seeing a problem where on two different motherboards, the card is plugged in and it doesn't show up AT ALL no matter how many times I reboot. We're running Linux, and using "lspci" to list PCI devices.

One is a Gigabyte board, the other is an ASRock motherboard.

Running "echo 1 >/sys/bus/pci/rescan" doesn't help.

I really need this to work for a customer who needs the Decklink Studio 4K for it's XLR outputs. Running Windows is not an option, our system is Linux-based!

Was this issue ever fixed? I am having the same issue on ASRock and Supermicro motherboards when using two DeckLink SDI 4K cards installed in the machines. Usually at least one card is detected, but the other card is usually not seen every other reboot.

I don't know if this is the same problem or another one, because I just bought the card and rebooted the pc only few times.
I have a Windows 7 pc on an old MB MSI.

I installed the card and all was fine. Another day I rebooted and I couldn't see the card, the next reboot instead it was seen correct...

I confirm this is the exact problem I have too!
For example, in my old MSI X58Pro-e, with W7 64 bit pro, I have this:
Start PC --> no detection
1° reboot --> OK
2° reboot --> NO
3° reboot --> OK
4° reboot --> NO
5° reboot --> NO

So, the problem is both on Linux and Win.
This is a very annoying problem.

Blackmagic, please solve this fast.

I have same issue with the 3 Studio 4K card I tested on ubuntu 12.04 and the issue is also present on 4K extreme cards.

Just to update that this is still a problem for us with the latest 10.3.5 drivers. We have also tried a new 4K card in the same chassis with no change in behaviour.

Another update to say the 10.4.1/10.4.2 drivers appear to fix this issue. The 4K card is now always present after reboots on our systems.

I confirm the problem is solved.
Long time but at last solved, good.
