Debugging Modules after 2.6.3 |
|
----------------------------- |
|
|
|
In almost all distributions, the kernel asks for modules which don't |
|
exist, such as "net-pf-10" or whatever. Changing "modprobe -q" to |
|
"succeed" in this case is hacky and breaks some setups, and also we |
|
want to know if it failed for the fallback code for old aliases in |
|
fs/char_dev.c, for example. |
|
|
|
In the past a debugging message which would fill people's logs was |
|
emitted. This debugging message has been removed. The correct way |
|
of debugging module problems is something like this: |
|
|
|
echo '#! /bin/sh' > /tmp/modprobe |
|
echo 'echo "$@" >> /tmp/modprobe.log' >> /tmp/modprobe |
|
echo 'exec /sbin/modprobe "$@"' >> /tmp/modprobe |
|
chmod a+x /tmp/modprobe |
|
echo /tmp/modprobe > /proc/sys/kernel/modprobe |
|
|
|
Note that the above applies only when the *kernel* is requesting |
|
that the module be loaded -- it won't have any effect if that module |
|
is being loaded explicitly using "modprobe" from userspace.
