| 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 |
