Kernel panic - unable to mount root partition Slitaz on ext3 on USB
  • colbencolben November 2010
    I want to have slitaz on my USB, but as an ordinary system with ext3. Kernel gets started, but I get a kernel panic "unable to mount root partition", kernel lists me the possible choices, but I don't see there the partitions of my USB drive. I suppose, it's because kernel is not compiled with some funcionality, which let's it to see the USB drives during the boot, is there some solution other than to compile my own kernel? Possibly some initramfs with some particular module? Could someone help me, pls? Thanks

    It should not be any problem - but with this little info its hard to help.
    Is it a laptop?
    is your computer able to boot from USB?
    did you install frugal or normal?
    did you check md5sum after downloading the iso?
    did the CD boot without problems?

    i have the same problem , i installed in usb drive (sdb1) Slitaz from a boot CD
    i changed the root(hd1,0) to (hd0,0) and dev/sdb1 to dev/hda1(in GRUB) , but i become kernel panic .


  • kultexkultex November 2010
    yes, thats cleer - because of this changing, SliTaz is looking for root in your IDE harddisk of the laptop - I guess its a laptop - you should not change

    i f i dont chage the the (hd1,0)= sdb1 i become
    error 15 dont finde file

    I have the same problem too when I try to install the 2.0 version. The kernel gives me the choice between sda1 (my DD on a laptop) or RAM1, RAM2, RAM...
    But it works perfectly when I install the 3.0 version (Xvesa iso, xorg refuse to recognise my display card)

    i have the Cooking 20101104
    i will try with a Xvesa version

    @afroman its quite difficult:

    the easy way (best for USB) - frugal installation see here: http://doc.slitaz.org/en:guides:frugal

    then copy /boot to hda1 - bzImage and rootfs.gz have to be on hda1

    and then cange grub to

    title SliTaz cooking
    kernel (hd0,0)/boot/bzImage rw root=UUID home=UUID vga=normal
    initrd (hd0,0)/boot/rootfs.gz

    to get UUID of the USB Partition type

    blkid /dev/sda1

    and you should have also a home direcroy

  • kultexkultex November 2010
    @afroman whats strange? normally it should be dev/sda1 and not dev/sdb1

    Installing Slitaz on USB Device
    If you want to install SliTaz on an USB device, you must give a little “rootdelay” to allow time for the Linux kernel to detect it.
    To include this option, edit your menu.lst to include the argument :
    title SliTaz GNU/Linux 3.0 (Kernel 2.6.34-slitaz)
    root(hd0,0)
    kernel /boot/vmlinuz-2.6.34-slitaz root=/dev/sda1 vga=normal rootdelay=10
  • afromanafroman November 2010
    yesssssssssssssssssssssss :-) 10x @ all
    it work now
    withe

    root(hd0,0)
    kernel /boot/vmlinuz-2.6.34-slitaz root=/dev/sdb1 rootdelay=10

    root(hd0,0) withe root=/dev/sdb1 it s not logical but it work

    10x again
