hi again,
now i've checked with an unmodified 2.4 kernel and sound was ok. with the 2.4
xen0 kernel following happens when trying to start alsa after the alsa-driver
was installed (with same xen0 kernel, sound-module was compiled in before and
doesn't make problems without the alsa-drivers installed). after the oops
i've to delete all xen0 modules in /lib/modules and install new to avoid
crashes when logging in as non-root (don't know why, alsa is not started
automatically and shouldn't be initialised when logging in as normal user).
once crashed, theres no chance to use other pci-devices like the described
isdn-card. the system will freeze when i'm trying to start a connection.
regards,
björn
