SuSE 8.1 - drive mapping & initrd w/ Kernel 2.4.22

Hi all,

I have two problems at once:

Problem 1

First thing is my dvd/cdrom and my cdwriter are somehow inoperable. I checked the links and they go to the correct devices, however when I place a disc in either device and try to mount it, it tells me it couldn't mount due to a bad filesystem or superblock !?

Problem 2

Second thing (this I am probably just too stupid for) is I compiled a 2.4.22 Kernel (not the first time I compiled a kernel), but this time on SuSE 8.1, which uses initrd for booting.
After compiling and installing I ran mkinitrd, but miracolously it only created new images for my standard suse kernel 2.4.19, not my new 2.4.22 one. I think I missed something, but couldn't find anything on this board nor in any groups.

Problem 2

Try running

mkinitrd -k "your_kernel_image_name" -i "initrd.your_kernel_image_name"


mkinitrd -k "bzImage" -i "initrd.bzImage"

Problem 1

SuSE tends to activate scsi emulation for all the drives it found (at least in my case), check the boot messages to see if its using scsi emulation or not (which probably will). If the emulation is enabled then your cd-r and dvd should be on "/dev/sr0" and "/dev/sr1", check if those blocks exist on the /dev directory and also check the "/etc/fstab" file to see if the devices are pointing to the correct block.

Ty very much ! I have been able to create an image for initrd now.

For problem number 1:
I found it was the scsi emulation and deactivating it solves my problem, however I need it for using my cdwriter. I pass the parameter for enabling scsi emulation at kernel bootup, however I limited it to hdg only (where my writer is, my dvd is on another controller). Why is it using scsi emulation for both drives? (I figure there must be another scsi init setting somewhere..)
