While attempting to install a CDR i discored an error in the way gentoo /etc/modules.autoload is processed (i'm assuming an init script error). Trying to get ide cdrom + a ide-scsi emulated burner to work, i have all the modules compiled: ide-cd, sg, sr_mod, scsi_mod, ide-scsi, cdrom. Now when i loaded the modules by hand in the folowing order it works: modprobe ide-cd ignore=hdd modprobe ide-scsi modprobe sg modprobe sr_mod now this works and /dev/hdc is a ide cdrom and /dev/sd0 is a scsi cdrom and i can burn stuff. Now if i edit /etc/modules.autoload so it's like this: ide-cd ignore=hdd ide-scsi sg sr_mod What happens is the ide-cd takes over both it ignores the (ignore=hdd) and the scsi cdrom driver, handles nothing. Now i concluded that this must be an error in the way /etc/modules.autoload is read, exectured, ... Now you might say that params are not supported, but look at the man page for modules.autoload: " The /etc/modules.autoload file contains the names of ker

thats odd, my modules.autoload works just fine for me ... <modules.autoload> ne io=0x300 ewrk3 irq=11 io=0x280 </modules.autoload> neither will not work if the IO and IRQ arent specified properly ... could you post the boot up screen ? when you load gentoo its gonna say something along the lines of: Loading module ide-cd Loading module ide-scsi just post exactly what is displayed on boot ... also, as soon as you get the login prompt, type `dmesg` and post the information that you see there ... if you can, try to pick out the information that is relative, but if you're unsure, just post it all

fixed by passing arguments to the kernel at boot time, strange because both are modules so they shouldn't be loaded in.
