iwlwifi crashes and produce a ~5-10s freeze

Hi

Recently I noticed rares but pretty long system freezes on my Archlinux laptop (XFCE)

Juste after the freeze, the corresponding journalctl entries are (errors only)

Note that my brother have the exact same laptop and also run Arch Linux and he has the same problem (same log).
So I think it's a kernel problem, not a hardware one.
