Hello to everyone, i face a problem when using embedded video call in Firefox or even if a watch a video in Vlc via popcorntime. System freezes completelly and i am not able to switch to tty so i unplug the power. If i disable swap i can kill firefox without system freezing. I have detected some suspicius lines in kernel messages and in coredumpctl but i have no idea how to resolve the issue and backtrace the problem.

My system:
Arch Linux with everything updated
Core 2 duo dual core T9400 @2.53 Ghz
4 Gb ram
Nvidia 9300m gs with the closed drivers
and I use a separate partition of 2gb for swap with the default swappiness 60%

Any help and ideas would be appreciated, thanks in advance!!
 


Im answering on my own so other people having familiar problems may get helped by this thread. The "marked with red" messages are related with the wireless card. The sollution is the same as other operating systems and you need to disable the n mode. But i dont think that this is resonsible for the freezes.

Here s the workaround from the Wiki: https://wiki.archlinux.org/index.php/Wireless_network_configuration#iwlegacy

Now about the freezes, the problem only presents onfFrefox usage. It seems that its the known problems with memory leaks on Firefox existing for years. I tested with chromium, it uses less than the half memory compared to Firefox and I ve no slowdowns no freezes, nothing at all. I can run multiple tabs or windows with videos very smoothly.

You can mark thread as solved! Thank you!!
 
Thanks for sharing, @leopseft , and welcome to linux.org :)

I am glad you solved it for yourself.

Enjoy your Linux :D
