Problem running 2 6902 on Debian Stretch (solved)

Problem running 2 6902 on Debian Stretch (solved)

Postby Boronsbruder » Sat Nov 18, 2017 3:47 am

Hi guys!
I'm trying to run two 6902 on my Debian Stretch Server with Tvheadend 4.2.4-23.
I did compile the driver using the wiki.
If the card on my first 4x-pcie-slot is activated the Server is running fine.
When i activate the 2nd card it takes some time and my SERVER crashes.
When swapping cards or activating only the card on the second slot the Server crashes too.

Code: Select All Code
Linux ZEROSERVER 4.9.0-4-amd64 #1 SMP Debian 4.9.51-1 (2017-09-28) x86_64 GNU/Linux


Debian, tvheadend and drivers should be the lastest ones.

Thanks for the help!

I took the drivers from here https://github.com/tbsdtv/linux_media/wiki

I'll try...
... but when running w_scan without using the -a Adapter option the server crashed again (because it used Adapter 2 and 3?)

*EDIT*
It did use the second card because the other one was used by tvheadend

*EDIT2*

Done -> Crash

All is good running two 6902 on Ubuntu 16.04 using open-source driver. Perhaps hardware or a Stretch problem?

Your goal is to see something like this before you even start TVheadend:

Looks like yours except showing up tbs5520se but i there is no TBS5220se connected. Maybe the Montage Technology M88DS3103 uses that driver (this usb tuner was not connected when the crashes occurred). I'll check this later.

I already tried turning on "Force pcie Gen1" in bios to eliminate compatiblity problems

My next steps will be:
- Unplug my Raid-Controller and plugging one of the cards in the pcie-slot to eliminate problems with the 3rd pcie-slot
- Connecting another power supply to eliminate lack of power

But that will be a little bit of work...

I got the problem solved.
After swaping cards it was clear that the problem was the 3rd pcie-port.
After resetting and reconfiguring the bios, the 2nd card seems to run without problems.

Thanks for the help!
