This line is in the documentation to enable scsi emulation for CD buring: echo -e "ide-scsi\nsg\nsr_mod" >> /etc/modules.autoload.d/kernel-2.4 where 'sg' use to be the name of the module built when SCSI support is selected in menuconfig. This has worked in the past without a hitch; however, the kernel build now seems to want to name 'sg' as 'scsi_mod', and the line above fails unless you replace 'sg\n' with 'scsi_mod\n' Reproducible: Always Steps to Reproduce: 1. 2. 3.
What kernel is this report on? Type and version (e.g. vanilla-sources-2.4.20) if possible. We have several kernels and this might be reflecting only a single kernel...

It is linux-2.4.20-gentoo-r7 (just installed, and that's what came down via emerge sync).
sg and scsi_mod are not equivalents. Both have a different functionality. Perhaps your kernel has sg inside the kernel? I haven't had any problems myself with the current docs (tested several kernels). On #gentoo I have received the same information, so I'm marking this as WORKSFORME. In the not-so-far future we'll add ATAPI burning support to the guides (just waiting for some cdrdao confirmation).
