/etc/init.d/pcmcia coding error (w/ rebuilt kernel)
Last modified: 2007-04-18 12:53:11 EDT
Description of problem:
After rebuilding a kernel from the kernel-source rpm provided, I noticed that
the pcmcia modules were not being loaded (reverting to the original install
kernel still worked). After hunting down a number of things, here's what I came
1. The kernel build/modules_install process creates a
/lib/modules/<kernel_tag>/pcmcia directory. The original (installed)
/lib/modules/2.4.20-8/ does not have this directory.
2. The /etc/init.d/pcmcia script keys of the existence of this directory and
executes a different syntax for 'modprobe pcmcia_core.' I thought it wasn't
possible (and I still think that), but calling 'modprobe pcmcia_core.o' will
fail (the '.o' shouldn't be there... see code below).
Here's the code block from the pcmcia script (with my comments added)...
if [ -d /lib/modules/preferred ] ; then
# MY COMMENT: THIS IS WHERE IT WAS MESSED UP.
# MY COMMENT: THE NEW KERNEL's modules directory had a
# MY COMMENT: top-level pcmcia dir which dropped into
# MY COMMENT: this first if block.
# The elif block is the right one.
if [ -d $PC ] ; then
echo -n " modules"
# MY COMMENT: how does this work? I think the .o
# MY COMMENT: shouldn't be there.
# MY COMMENT: Looking at the same script for Redhat
# MY COMMENT: 7.3, the lines have "$PC/" prefixing
# MY COMMENT: the module name like so...
# MY COMMENT: /sbin/modprobe $PC/pcmcia_core.o $CORE_OPTS
# MY COMMENT: This makes _more_ sense, but I don't think
# MY COMMENT: it'll work.
/sbin/modprobe pcmcia_core.o $CORE_OPTS
/sbin/modprobe $PCIC.o $PCIC_OPTS
elif [ -d $KD ] ; then
echo $" module directory $PC not found."
I can fix it either by modifying the script or blowing away the
/lib/modules/<kernel_tag>/pcmcia directory (since it just contains symlinks
to the kernel directory versions.
Version-Release number of selected component (if applicable):
Standard RedHat 9 (Shrike) release.
Recompiling everything now... but, assuming the error is in the pcmcia script,
then it's not a kernel compilation error, it's a script logic error.
Steps to Reproduce:
This was fixed in an update to FC1, and in current trees.
