cx23885 risc op code error with DvbSKY T982

I have dvbsky T982. The firmware is up to date from openelec site. Nothing on the CI slot

Linux xpc 4.1.0-rc8 #2 SMP Sun Jun 21 11:16:21 EEST 2015 x86_64 x86_64 x86_64 GNU/Linux I run the kernel in ubuntu

dmesg from the startup

I've got a couple of T982 cards. Running Debian Jessie, with kernel 4.1-rc8, I cannot reproduce your errors. Only difference might be:
I synced the silabs drivers with upstream and used the patch from:

http://git.linuxtv.org/cgit.cgi/media_tree.git/patch/drivers/media/pci/cx23885/cx23885-dvb.c?id=ee3c3e46885946cc041f08ec68e7c5b91b087cbe

Cheers,
Tycho.

hi,

I tested with 4.1.0 (which produced the errors. 4.1.0 with media_build produced the errors. I did not test that with the patch, as because of another kernel bug (in mdraid) I switched to 4.0.6.

With 4.0.6 this error does not seem to happen with neither card.

yours,
Jouni

Just as I reported, it happened. Then I got the media_build driver from Jun 25 (which seems to include the IF selection patch), and there it happens again...

Do you actually see any visual artifacts, or is it just messages in the log?

Regards,

Hans

hi,

I am pretty certain that these are minor problems. The cards seem to work fine after the messages, so I would not call this urgent. Some recordings have visual artefacts, but I do not know whether they happen because of these events or because of the broadcast transmission or for some other reason. These occur every few hours in the log/ or a few times a day (with three cx23885 based cards on the PCIe bus).

I started to look at the driver as for 3.19 kernel coming with ubuntu (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1451009) the cards seemed to crash. For 4.0.6 and 4.1.0 the cards work, but as I was already looking at this, I decided to report these.

If you think these messages are not worth more effort, I am OK with it.

yours,
Jouni

hi,

I was pointed out that my message sounds inappropriate and as demanding an (immediate) answer. My intention was just the opposite - to tell you I am not going to flood the mailboxes of the list members unnecessarily.

Here the offending line:

I am sorry about this.

yours,
Jouni
