Salut @ tous,
J’ai un soucis avec mon PC portable Dell XPS L702x.
Le lecteur SD card ne semble fonctionner que lorsqu’une SD card a été insérée dés la phase de boot.
D’après ce que j’ai lu sur la toile, certains périphériques utilisent le PCIE hotplug pour changer les états des périphériques en réponse à des évènements du type insertion d’une carte SD, …
Cependant, les fabriquants ne fournissent pas de firmwares pour supporter ce fonctionnement. Par conséquent, le workaround serait de passer l’option pciehp.pciehp_force=1 au kernel.
Je l’ai donc ajouté à mon /etc/default/grub dans la variable GRUB_CMDLINE_LINUX_DEFAULT et lancé l’update-grub. Cependant ça n’a pas l’air de fonctionner.
Je suis sous debian wheezy kernel 3.0.0-1-686-pae.
