    Re: Blessable Boot Partition

    when do i type this?
    Code:
    (initramfs) cat /proc/partitions
    (initramfs) ls /dev/sd*
    in the first 3 seconds, when there's a bunch of text, i spotted a few errors.
    i had to write these quickly, so they might not be word for word.
    Code:
    can't find irq for pci int a: please try using pci=biosirq
    found hc with no irq
    init (something) failed -19
    ohci1394 failed to allocate interupt 0
    Probe of (something) Failed with error -12
    Driver sd needs updating. Please use bus_type methods
    i've been using the package you uploaded. I re-downloaded it just in case, but it still didn't work

    Re: Blessable Boot Partition

    Were you able to check the partition names?

    Ah sorry, do that after you get the alert, hit a key, it should
    go to
    (initramfs)

    Those errors might be a clue but probably not fatal, IDK.

    It all looks correct as far as loading the kernel, there is something stopping the root partition from being mounted by linux, and I cant see how the booloader can cause that, it is loading the kernel from the same partition, but grub is using its own modules to do that.
    And the linux side seems to be ok when old grub1 is the bootloader.

    I will have to leave it there for now, will check back after a sleep.

    Re: Blessable Boot Partition

    what key should I use? I think i hit every key on my keyboard, and not one of them made it so I could type.

    /proc/partitions does not exist
    /proc is completely empty except for . and ..

    Re: Blessable Boot Partition

    Had another look here, I think try adding the kernel arg
    pci=biosirq
    maybe for the macbook santa rosa.
    It does no harm here for macbook2,1

    It is established that (hd0,4) and /dev/sda4 are correct.

    PM me if that might make it easier.

    re-reading - you said it is a MacBook 2,1 but SantaRosa is 3,1-4,1 according to the wiki?
    (Mine is a 2,1 with 80GB hd).

    Re: Blessable Boot Partition

    On macbook2,1 I can reproduce the bug you described by setting acpi=off in the kernel boot options. It is an acpi issue.

    That causes both the < ALERT... cant find /dev/sda4 ... dropping to shell>
    AND the continuous looping of the ata5 timeout, with keyboard dead,
    so you cant do anything except power off.

    So to allow acpi to work, try acpi=force in the meuentry

    Code:
    linux /vmlinuz root=/dev/sda4 video=efifb agp=off acpi=force
    I can't test that here because I have to use acpi=off to reproduce the bug.
    pci=noirq had no effect.

    For a list of the boot options and other acpi settings -

    Re: Blessable Boot Partition

    I'm sorry, I had been told it was a Santa Rosa. My mistake.
    I looked it up, and the T7400 processor is not a Santa Rosa one.

    acpi=force made no difference. neither did pci=noirq.
    acpi=noirq or pci=acpi did not work either.

    Use the information in the "Before you post" link to properly identify your Mac.

    Try this menuentry
    It should get to (initramfs) but no keyboard.
    Code:
    menuentry "search-vmlinuz root=sda4" {
    	search --set  /vmlinuz
     linux  /vmlinuz root=/dev/sda4  agp=off video=efifb  break
     initrd  /initrd.img
    }
    I want to get this fixed, here is some info I nead .

    1. The macbook model:
    from macosx -
    Code:
    Apple--About this mac--More Info:
    
    Hardware Overview:
    
      Machine Name:	Mac
      Machine Model:	MacBook2,1
      Processor Name:	Intel Core 2 Duo

      Memory:	1 GB
      Bus Speed:	667 MHz
      Boot ROM Version:	MB21.00A5.B07
      SMC Version:	1.13f3
      Serial Number:	W8717FYXWGL
      Sudden Motion Sensor:
      State:	Enabled
    2. About the ubuntu installation on sda4.

    How was this installed, and what kernel versions are on it, and can you still boot it with grub1 - we should fix that first.

    You can list the boot files fronm the efi grub command line
    Code:
    search --set /vmlinuz
    ls -l /boot
    It must be intrepid 810 kernel version 2.6.27 to work with EFI, and i386 not amd64 for that build of grub.efi. An intrepid server or alternate install CD ia best.

    3. It seems that nothing is affecting the result.
    When you tried acpi=off and others, booting from the grub editor must be done using the fn and F1 keys (on my macbook), without escaping to the menu, else it will cancel the edit. It is safest to edit a menuentry in macosx. Can we eliminate that suspect.

    Re: Blessable Boot Partition

    Last night, I had been thinking about it, and realized it might be because I'm using the 64-bit version of Linux.

    I just recompiled grub because of this, and now I have the exact same problem I did in post 5 of this thread.
    I can no longer use grub2 at all, so I can't test that new menuentry.
    Is this the correct way to compile/install it?
    Code:
    ./configure --with-platform=efi --target=x86_64
    ./grub-mkimage -d . -o grub.efi gpt hfsplus fat ext2 normal chain boot configfile
    cp grub.efi *.mod fs.lst command.lst /media/HD_2/efi/grub

    2.kernel is 2.6.27-9-generic, but 2.6.27-7-generic did not work either
    It is Ubuntu 8.10 AMD64 with the alternate text-based install
    grub1 still works.

    3. I had been using F1, and editing the files in OSX, so that is not a problem
