[hsflinux] Re: hsfmodem incompatible with official debian kernel 2.4.21 ?

Hi Marc,

The kernel oops is probably caused by the modules being compiled
with a gcc whose major version number differs from the one used to
build the kernel; most likely the new kernel was built with gcc 3.x
and the modules were rebuilt on your system with gcc 2.x.

I am enclosing an improved kernelcompiler.sh script (to be included
in the next release) which should prevent this from occuring.
You should copy it over the old one (under modules/ in the tar archive
and/or /usr/lib/hsfmodem/modules/) before rebuilding the modules with
hsfconfig -k.

Yours
Marc
