Re: Comment recharger un module noyau planté ?
Bonjour,
Ça faisait longtemps que mon module wifi n'avait pas planté, donc pas eu l'occasion d'essayer les remèdes.
Le 14/03/22 à 18:21, Hugues Larrive <hlarrive@pm.me> a écrit :

Cette commande a été assez longue a rendre la main, elle a sorti qqchose dans kern.log, mais je
n'ai pas cette trace car
> echo 1 > /sys/bus/pci/rescan
a complètement planté le système, et après le reboot hard qui a suivi y'avait plus les traces
précédentes.
