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
|
