Full syslog from the boot
This is complete syslog.
The message I pasted at the start of bug report repeates many times, and at a certain point one different comes out
(this part)

plus other ones (that I'm not able to understand)
and in the end also messages about hard disk:

Try this tree: http://git.linuxtv.org/hverkuil/media_tree.git/shortlog/refs/heads/saa7134 It's just the last three patches that you need, although I am not 100% certain if they will apply cleanly to a 3.14 kernel. You might have to use this whole tree instead if they don't apply. It's a complete rework of saa7134 that is planned to be merged for 3.16. It's likely that this will fix this crash.

I put it again, there was a problem of text format.

Full syslog from the boot - Kernel media-tree
I tried with the entire tree. I made a make oldconfig with my 3.13.6 file, but it asked many questions (it seems to be rather different... in Makefile I saw it's labeled 3.1.0). I answered all the questions with default.
A good thing is that it doesn't suffer from the suspend-resume issue.
But the crash of this report happens the same. It's better than 3.13.6, because it remains in "media" (3.13.6 went beyond).
Note: xawtv is unkillable, even with "kill -9".
Now check out the saa7134 branch and try again :-) You're using the master branch which is indeed 3.1 and two years old... I'm not familiar with trees and branches, developement sites seem a jungle to me ;-) I'm not able to find a "saa7134 branch". Is it an entire tree that I can git at a time? Or is something I have to mix with some other? Have I to git this? It says "latest drivers for V4L/DVB/Remote Controller" http://git.linuxtv.org/media_tree.git Thank you. Go to the git tree you checked out earlier (with the 3.1 kernel), then do: git co -b saa7134 origin/saa7134 If you do 'git log' you should see 'saa7134: convert to vb2' as the last commit. It stops, saying that "co" is not a git command. If it's simpler, I can try to clone the entire updated tree... but I'm not able to find it. My best find is this page, http://git.linuxtv.org/hverkuil/media_tree.git/tree/saa7134, but I don't find any link I can give to git. Argh, sorry. 'co' is my git alias. Use 'git checkout' instead. I'm so used to typing 'co' that I forget that it is not a standard git command. I've tried, this branch works :-) The stuck window (xawtv) remains stuck, but 1) It's killable with a simple kill 2) Does not generate kernel events 3) When xawtv is stuck, other applications (i.e. kaffeine) can access the driver and see TV channels. So it seems that what remains is something related to the xawtv application and not to the kernel module. I've also found this report that I find very similar to mine. https://bugzilla.kernel.org/show_bug.cgi?id=16298 This made me understand that it was not xawtv + tvtime, it's in general "xawtv + something other opèened at the same time". And even for this report (double xawtv) the new saa7134 solves the problem, while the old crashes. This is a duplicate bug report. *** This bug has been marked as a duplicate of bug 73361 *** |
