Package: kernel-image-2.4.27
Version: jensen.1.0
Severity: normal
The patch has already made public in 1998
(http://lkml.org/lkml/1998/8/9/16) and again in 2003
(http://linux.derkeiler.com/Mailing-Lists/Kernel/2003-10/2341.html). I
am running the adapter ever since in my Jensen Alpha and it had been
working just fine during the last 10 years.
Now, since I posted the patch twice to the linux-kernel mailing list
without having any snippet of the code getting into the official kernel
I wonder if it could at least be possible to include it into a patch
set. Currently, I keep the patch in a file 998_lne390.c.diff.bz2 and
configured it as a patch set for "2.4.27-10sarge8".
Here comes the patch:
