Driver voor LSI 1068E laden

[_eXistenZ_]

Hallo,

Ik heb thuis een Gentoo-NAS (kernel 3.2.1 x64) waar ik een LSI 1068E op aan de praat probeer te krijgen.

vandaag heb een SuperMicro UAC-USAS-L8i binnengekregen, welke gebaseerd is op deze chip, een chip die voor zover ik gelezen heb goed ondersteund wordt in Linux, er is zelfs een open source driver in de kernel beschikbaar.

Ik krijg echter het volgende als ik modprobe mptsas doe:

# modprobe mptsas
FATAL: Error inserting mptsas (/lib/modules/3.2.1-gentoo-r2-mk2/kernel/drivers/message/fusion/mptsas.ko): Unknown symbol in module, or unknown parameter (see dmesg)

Het bekijken van dmesg geeft mij dit:

# dmesg

De kaart wordt wel gezien al:

Je module dependencies zijn fubar, er worden bepaalde modules niet ingeladen waardoor je unresolved symbols krijgt. Misschien te fixen met depmod -a, maar anders zal je verder moeten zoeken, of het probleem ligt aan je kernel module installatie, of aan je module-init-tools installatie.

Inmiddels opgelost, ik had de volgende kernel-opties nodig:

$ cat .config | grep =m
CONFIG_SCSI_WAIT_SCAN=m
CONFIG_SCSI_SAS_ATTRS=m
CONFIG_FUSION_SAS=m
CONFIG_FUSION_CTL=m

Dit maakt de volgende kernel-modules:

$ lsmod
Module                  Size  Used by
mptsas                 34545  6
mptscsih               19966  1 mptsas
mptbase                60335  2 mptsas,mptscsih
scsi_transport_sas     26510  1 mptsas

Blijkbaar wordt er ook in de kernel zelf nog wat gecompiled / enabled, want mptsas heeft scsi_transport_sas nodig, maar die wilde op zijn beurt met mijn oude kernel ook niet laden. Daarom deze modules aangezet, nieuwe kernel gemaakt en geinstalleerd, en alles draait als een zonnetje
