    mkinitrd -o /boot/initrd.gz
  4. reboot and try using the generic kernel

The command in bullet #2 should create a valid mdadm.conf file in your initrd-tree area. The command in bullet #3 should rebuild your initrd using only what is in your initrd-tree.

Please let us know if that worked. If it doesn't work, please tell us what was put into /boot/initrd-tree/etc/mdadm.conf after you ran the command in bullet #2.
Sorry for the late response, I only found some time now doing some extensive testing. Here's what worked for me.

Once the installation is finished, chroot into the newly installed environment.

Generate mdadm.conf:
Code:
# mdadm -E -s > /etc/mdadm.conf
Edit /etc/mkinitrd.conf and set RAID="1" (meaning "yes" and not the RAID level)

Generate an initrd:
Code:
# mkinitrd -F
Speed up disk synchronization:
Code:
# echo 50000 > /proc/sys/dev/raid/speed_limit_min
Edit LILO, exit and reboot.

With a RAID 1 setup, rebooting can be done even when the disks are not yet synchronized. With a RAID 5 setup, disk synchronization has to be finished, otherwise you get a kernel panic on reboot.

Now everything works like a charm.

I humbly suggest a little update for the official Slackware RAID documentation. Some stuff is missing.

Cheers,

Niki
