Keep disabling features and try a different kernel version (the one that worked with other distros) until you pinpoint the problem. The only hints you got are the panic backtrces and boot output. Then file a bug. As for dumping the boot output if you can't get to userland I think the only way is with a serial or net console. Also look at CONFIG_BOOT_PRINTK_DELAY, it can setup a delay before every printk message so you at least get time to read it. -- Fernando Rodriguez
Re: [gentoo-user] Firefox 49.0 & Youtube....Video: Yes - Audio: No...
I just got Firefox to play HTML5 pages (and likely other stuff as well),
with audio working, my system.
But let me first vent my frustration for why it was so hard...

It took me such long time, well, yes, because ALSA had advanced and I
kept the old config, simply because it worked with all apps (but not the
Firefox, more below...)...
What other conclusion could a not very advanced user get but this one

How on Earth would a non-advanced user know after reading that Mozilla
bug, that she/he don't need to get that another layer for suspicious
purposes onto their fine ALSA?
Now I'll explain what was the reason it did not work (because I promised
I would ;-) and you were kind to offer help)...

No, jack was not needed, but according to:
https://wiki.gentoo.org/wiki/ALSA#JACK_audio_connection_kit
is far superior to pulseaudio, just to make clear. The below wasn't
needed for me to solve my issue.

(that's old config, maybe 2-3 or more years old. It just worked all the
time, who cared... MPlayer, Vlc, the old cinch cables --the RCA IIRC--
could get the recordings from old/new equipment... So who cared...)
So one of my two issues was exactly this one (and the change to make):
https://wiki.gentoo.org/wiki/ALSA#Firefox_and_YouTube_have_no_audio_with_custom_.asoundrc_but_other_apps_do
And after making the other change first, which is simply what Gentoo Firefox
Wiki says at:
https://wiki.gentoo.org/wiki/Firefox#Lack_of_sound
so after:
# emerge gst-plugins-meta:1.0
and changing my ~/.asoundrc to:
defaults.ctl.card 0
defaults.pcm.card 0
(or it will be
defaults.ctl.card 1
defaults.pcm.card 1
sometimes, in my case)
only then did Firefox finally start to play both video and audio when I
opened HTML5 pages.
A quick test was this page (but on my offline Apache, saying it because
I need to propagate the change to this clone that I access online with,
I did the changes on my maste machine, so if all keeps well when into
clone, I won't need to inform of some functionality still not there)
(doing the one-liner below worked):
$ firefox
http://www.CroatiaFidelis.hr/foss/cenz/iskon-t-com-miro-rovis/150320-17h_T-com_davi_ugovorima.webm
(that's actually a one-liner, only wrapped in mail)

[gentoo-user] HTML5 player (YouTube) is a pain!...Alternatives?
Hi, I get sick of this [CESNORED] HTML5 stuff coming from YouTube! Most of the videos while playayaingnaying arereare stututterutering liiklike helellell. I tested a lot of HTML5 addons to fix that problem and googled around the world but nothing helps. The only thing I found is an iconic sentence, which is true in this case also: "You are not alone...!". Is there any way to feed the stream from youtube direktly into a not blown player like mpv/mplayer or such (I would prefer not to load a complete gui (vlc) with any click again and again.)? Thanks for any help in advance! Cheers Meino PS: For the completeness: I have tried to fix that problem by: Restarting firefox Disabling hardware acceleration Disabling webgl Checking, whether the YouTube-testpage shows "all ok" for HTML5 (it does) Checking various about:config-setting for usefulness De-/Installing various addons, which all promise the heaven on earth

I've been running the youtube-flash-player Firefox addon https://addons.mozilla.org/en-US/firefox/addon/youtube-flash-player/ for several months now with decent results. It just reverts YouTube back to the old Flash video player. It's been working well for me.

This was my (painful) workaround the last days. I woyld like something like: Click on youtube-url, a window (console) pops up and starts to watch the video directly. Is it possible somehow?
