disagrees about version of symbol filemap_fdatawrite

[kniepbert]

Hallo *,

ich habe ein Problem mit meinem frisch gebauten XEN-Kernel.
Soweit lief eigentlich alles glatt, nur kann ich keine loop-Devices mounten.
mount -o loop fragt nach dem Modul und ein "modprobe loop" gibt:

Code: Alles auswählen

# modprobe loop
FATAL: Error inserting loop (/lib/modules/2.6.27.5/kernel/drivers/block/loop.ko): Unknown symbol in module, or unknown parameter (see dmesg) 

Im Kernel habe ich im Bezug zu Loop folgende Einträge:

Code: Alles auswählen

chieftec:/usr/src/linux-2.6.27-xen.hg# grep -i LOOP .config
CONFIG_BLK_DEV_LOOP=m
CONFIG_BLK_DEV_CRYPTOLOOP=m
CONFIG_XEN_NETDEV_LOOPBACK=y
chieftec:/usr/src/linux-2.6.27-xen.hg# 

Was fehlt mir da...?

dmesg:

Du solltest deinen Kernel mit einem neuen Tag neu kompilieren und den neuen starten.

Du hast bei einem Update wohl die API gebrochen und nun hast du dort versch. Versionen von Modules <=> Kernel interna.
