[LAU] RME Digi96: probe of 0000:06:01.0 failed with error -12

[mat]

Hi there,

i have a strange problem with my soundcard when boot
sometimes (others times it works well), i cannot start jack because it
just doesn't find the pci card at all!

so i checked the log and found this error : 

RME Digi96: probe of 0000:06:01.0 failed with error -12

i guess it has something to see with modprobe and 0000:06:01.0 should be
the mac address of the card ?? or something like that so i guess it's
unable to load the firmware??

i tried to remove & reinstall alsa-firmware-loaders with no results 

here is my /etc/modules.conf 

# ALSA portion
alias char-major-116 snd
alias snd-card-0 snd-rme96

# OSS/Free portion - card #1

alias sound-service-0-1 snd-seq-oss
