This script has a problem when we have more than one set of kernel modules in /lib/modules. The insmod may fail because the script uses 'find /lib/modules' to get the full path to the kernel module in real_mod_path(). The problem is when you have vmlinuz2 loaded into memory and you want to load the 'xxx' module, the script will load /lib/modules/vmlinuz1/xxx.ko instead of /lib/modules/vmlinuz2/xxx.ko. Just because the wrong 'vmlinuz1' subdirectory will be found before the right 'vmlinuz2' subdirectory by the find command. All you have to do is to search in the right subdirectory. To fix the bug, edit the modprobe script and do that: replace find /lib/modules | grep /"${1}${KSUFF}" with find /lib/modules/${KV} | grep /"${1}${KSUFF}" Reproducible: Always Steps to Reproduce: 1. make an initramfs that can work with more than one kernel 2. 3. agaffney@gentoo.org 2008-02-02 16:36:09 0000 Well, you are using genkernel's initramfs in an unsupported way. You can't really complain that it breaks :P However, the proposed fix is simple and appears harmless even for "supported" configurations. fdbugs@dupoux.com 2008-02-02 16:49:41 0000 Hi Andrew, Thanks for your quick reply. That's right this is an unsupported usage, but it's always better to have a program that works in all conditions. That's just a small contribution to improve genkernel. Hope you can include this patch in the next genkernel version. Thanks. agaffney@gentoo.org 2008-02-02 17:34:34 0000 This is fixed in SVN. Thanks. wolf31o2@gentoo.org 2008-02-14 04:32:41 0000 I just released genkernel 3.4.10_pre1, which has this fix included. Feel free to REOPEN this bug or make a comment if it is not resolved.
