Can you send the following information? - ls -lR /sys/bus/pci/slots - lspci -vvvv (as root user) Regards, Kenji Kaneshige (2011/10/11 17:11), Abdelghani Ouchabane wrote: > >>>> After I plug my board in, I executed echo 1> /sys/bus/pci/rescan >>> >>> >> >> Can you try echo 1 > /sys/bus/pci/slots/XXX/power? >> (XXX: slot number) > Hallo Kenji, > > I am still having the same problem after executing "echo 1 > /sys/bus/pci/slots/0000\:02\:00.0/power" > >> >>> It seems like a pciehp bug that you have to rescan explicitly.
