I wanted to try demudi so I downloaded an iso and burned it to disk (demudi-install_1.2.1-rc2i386.iso)

No problem with installation until reboot when it says:

ERROR: Removing 'alim15x3' : Device or resource busy
ERROR: Removing 'amd74xx' : Device or resource busy
ERROR: Removing 'atiixp' : Device or resource busy
ERROR: Removing 'cmd64x' : Device or resource busy
ERROR: Removing 'cs5520' : Device or resource busy
ERROR: Removing 'cs5530' : Device or resource busy
ERROR: Removing 'cy82c693' : Device or resource busy
ERROR: Removing 'gneric' : Device or resource busy
ERROR: Removing 'htp34x' : Device or resource busy

etc......... the list continues with different names being removed and at the end it says:

pivot-root: No such file or directory
/sbin/init: 431: cannot open dev/console: No such file
Kernel panic - not syncing: Attempted to kill init!


What is wrong? I cannot boot the system after restart.
Thank you for all your input.

You can ignore the error messages... The stock kernel loads all IDE chipset drivers by default. These can't be removed after they are loaded, but the hardware autodetection tries to remove all unwanted modules. The error message at the end indicates that the root device is not found. Before you boot, hit 'e' on the default boot stanza in grub. The lines root (hd0,4) and root=/dev/hda5 should point at the same device. Grub counts from zero and linux counts from a and 1 thus:
root (hd0,0) => root=/dev/hda1
root (hd1,4) => root=/dev/hdb5

Thanks, but I'm afraid I don't quite understand the procedure. I edited the lines as you've suggested
(root (hd0,0) => root=/dev/hda1
root (hd1,4) => root=/dev/hdb5
but it just ain't right, I still can't boot into Demudi.

Maybe some details about the HDD will help.
