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
