Since yesterday, I am having regular total freeze of my OS, archlinux, with no clear reason why.
The only thing I'm doing is browsing the internet with Firefox while it happens.
The audio, bluetooth are still working during these freezes, but I have no way to interact with the system...
I tried to find something helpful in the system log:
$ sudo journalctl -b -1 -k -xe

These freezes did not occur after a system update (it was last updated about a week ago) and I updated my system since to try to fix it but without success.
What can I do to diagnose and try to resolve this ?
Thanks !
