si2183 5-0067: read_status failed=-11

Dear All,

I bought a tbs5520SE some time ago, and it was working fine on an old computer running ubuntu 17.04.
I have bought a new pc with an i7, retored by laptop operating system on it, and noticed that:
- my tbs 5927 was working fine
- my tbs 5520se (seen as 5521 in the syslog!) was causing some errors si2183 5-0067: read_status failed=-11

(even when this not working, my old laptop works pretty well with the same tbs cards/dish, so this is not a tuner or dish issue)

I then decided to reinstall from scratch my new PC i7:
- installed a Ubtuntu 18.04
- reinstalled tvheadend
- recompiled the tbs drivers

and..... I got the same error si2183 5-0067: read_status failed=-11
Thsi error is a bit random, sometimes after running tvheadend I get it, sometimes I do not get error.

Not knowing what to do anymore, I played a bit and I noticed that after a reboot, if I run tvheadend once in crash mode (-A parameter), and then run tvheadend normally, I do not get the error anymore!

What could it be?

PS: tvheadend is started by using a proper udev configuration, waiting for the tuner devices to be available before starting tvheadend. So it is not a timing issue, but seems related to the drivers.

Any idea on how to fix this ? Driver issue? I saw something about IR remote control (that I do not have), do I need to change the driver code?

Thank you.

Regards,

Hi,

I can confirm that issue.

It is reproducible by switching from dvb-c to dvb-t2 which is okay but switching back from dvb-t2 to dvb-c produces the mentioned error. Done via tvheadend, no dvb-apps nor dvb-tools.

I stopped tvheadend for about 10 minutes. after that and starting tvheadend again the error disappeared. Maybe tvheadend tries to grab epg data from all enabled sources. If I'am watching channel X on dvb-c and tvheadend tries to grab on dvb-t it will fail. Then it would be an configuration / tvheadend issue and does not belong to this forum.

The meaning of "-11" is "EAGAIN" or "EWOULDBLOCK". There are at least two positions in si2183.c, si2183_set_frontend (set_params failed) and si2183_read_status (read_status failed) which check boolean type variable "active" of the device struct.

Same here, after every restart I would get these mesages in dmesg and tuner would not work:

TVHeadEnd is stopped for few minutes, error messages stop

TVHeadEnd is started:

The only way to stop them is stop TVHeadEnd for few minutes and start it again.


If I unplug the TBS5520SE and restart the machine, everything work as should and no error messages are displayed,
so that indicates it is TBS tuner specific error ..........

This ridiculous, contacted support, first said maybe enough USB power. When I said i have both ports connected to USB 3.0, they said device is not compatible with USB 3.0 ports and only compatible with 2.0 ports

It's funny cause my understanding that USB 3.0 is fully backward compatible with USB 2.0 (given OS supports it), and lsusb already detects it:

It's a great piece of hardware, but the constant problems after kernel update are very annoying :(
