I'd think that saying "noprobe" means > "do NOT probe" - but it probes anyway. If your kernel uses modular IDE drivers and an initrd/initramfs that loads them, your result is the expected one (i.e.: not a bug). One should add the following or similar options into /etc/modprobe.conf in the initrd in order to get the result: options ide_core options="ide0=noprobe hda=noprobe hdb=noprobe" If you don't use initrd, or have a non-modular IDE driver, please ignore this message. -- Alexander E.
