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