Can't scan (Kernel 2.6.39-5)

[pspmann]

Hello,

I recently buy a TBS5922 and I received it today.
I use Debian squeeze with 2.6.39-5 kernel (from squeeze-backports).
When i try to scan with my-tv or kaffeine : it freeze (the program) around 17% (he finds channels) and the LED changes color: a green moment, another red. I need to restart.

dmesg when i put my receiver :

EDIT 2 : I tried with kernel 2.6.38-8

Scan works better but it stop to 57% and kaffeine/metv freezes. (Led green..)
Kaffeine says : "dvbdevice::frontendevent : tuning failed"

Thanks.

Hi,

I observe the same behavior with the scan tool from the DVB Apps. It scans and finds about 800 channels and crashes then. The crash occurs reproducibly at the same frequency.

Thanks
Lutz

Same result with Ubuntu 11.10 (Kernel 3) .... and new drivers published yesterday. It blocks always to the same point and "lock" led turns on ... turns off ...

A part of the log : (dmesg)

Steven,
are TBS working on that issue? The box runs under mythtv without problems but since the scan is not working correctly I only get a couple of channels. BTW: Scanning with mythTV crashes the FW as well. Is there any workaround? Do you have an Idea when you will fix that? I'm thinking of buying a TBS6984 but I'm worried that I get the same issues there...
Regards
Lutz

Steven, are TBS working on that issue?

no, because there we don't have such issue:

- for example it seems user "pspmann" has faulty box - it's even more strange that it seems he's using some test driver, because messages like "DEBUG: 5922 tune checked" and "DEBUG: 5922 tune sent" are available only in test driver, which should has been given to him by TBS support and his tests clearly show something is not right with his 5922 hardware and probably it was requested to him to return the box for replacement or it has been already replaced

- that means your problem is entirely different than "pspmann". so, it could be some less general hardware fault, which causes instability or indeed some software issue

BTW: Scanning with mythTV crashes the FW as well. Is there any workaround? Do you have an Idea when you will fix that?

if it crashes always on the same place during scan most probably that line in your "conf" file for the scan on which it's crashing is wrong and you need to delete it. also, what's the error message after all there is a crash and thus has to be some error reported in 'dmesg'.

I'm thinking of buying a TBS6984 but I'm worried that I get the same issues there...

you won't, whatever problem you have it's isolated to your 5922 box or some problem with 5922 drivers (which is less likely).

[pspmann]

Hello,

I don't use test driver, only official driver which is available on your website.
No problems on Windows.
I'm trying to find a solution with EU support.

Hi Codi

if it crashes always on the same place during scan most probably that line in your "conf" file for the scan on which it's crashing is wrong and you need to delete it. also, what's the error message after all there is a crash and thus has to be some error reported in 'dmesg'.

What "conf" file are you refering to? Can you please explain in more detail what to do? I try to post dmesg log on monday but I'm sure it looks like the one pspmann posted already.

Im quite sure that this is a fw/driver issue since the card works without issues under windows. I'm currently using the card with the very limited set of channels it found during the scan and it works without problems. Please have a look at that otherwise the box is useless for me.

Thanks

[luni]

I also get those messages in the logfiles. BTW this really floods my /var/log .... (I use the driver from your web site)

[1450394.275340] DEBUG: 5922 tune checked
[1450394.331214] DEBUG: 5922 tune checked
[1450394.387233] DEBUG: 5922 tune checked
[1450394.443215] DEBUG: 5922 tune checked

Looks like you have a DEBUG version of the driver on the net !?! I still think your box is a great product if only the driver would work correctly (scanning, logging....)

I dont' know why the drivers aren't GPL - if they were it would be easy to debug the code or at least give some additional information to the developers for code improvement.
