Ubunutu Mate 26.04 | Kern

Hej,

Jeg har opdateret min HP Omen fra 24.04 til 26.04 Ubuntu Mate.

Under 24.04 havde jeg ingen problemer, men i 26.04 skete der en del.

Diskforbrug: Min disk blev hurtigt fyldt op og fandt frem til kern.log

Løsningen var at sætte iommu = off i grub.

Problemet ser ud til at skulle findes i IWLWIFI.
