1 | Debugging Modules after 2.6.3 |
2 | ----------------------------- |
3 | |
4 | In almost all distributions, the kernel asks for modules which don't |
5 | exist, such as "net-pf-10" or whatever. Changing "modprobe -q" to |
6 | "succeed" in this case is hacky and breaks some setups, and also we |
7 | want to know if it failed for the fallback code for old aliases in |
8 | fs/char_dev.c, for example. |
9 | |
10 | In the past a debugging message which would fill people's logs was |
11 | emitted. This debugging message has been removed. The correct way |
12 | of debugging module problems is something like this: |
13 | |
14 | echo '#! /bin/sh' > /tmp/modprobe |
15 | echo 'echo "$@" >> /tmp/modprobe.log' >> /tmp/modprobe |
16 | echo 'exec /sbin/modprobe "$@"' >> /tmp/modprobe |
17 | chmod a+x /tmp/modprobe |
18 | echo /tmp/modprobe > /proc/sys/kernel/modprobe |
