Hi everyone,
I already tried it somewhere else, but as no one knew help, I hope it
is ok to bother you, too ;)
I am trying to boot my Dell Latitude X1 netbook into a CompactFlash card.
The system is debian squeeze.
The card is inserted into the netbook's built-in CF card slot, which
apparently is connected internally through a Pcmcia adapter.
Because the netbook is not able to boot from the card itself (it does not
show up in the netbook's BIOS bot menu), I have a
spearate /boot partition on the netbbok's internal HDD (on /dev/sda1).
Now, when I boot into the squeeze install on the HDD (on /dev/sda2), the
CF card is detected as /dev/hda and appears to work flawlessly.
So I copied the squeeze install onto the CF card (/dev/hda1), with
the /boot partition on /dev/sda1, and try to boot this, however the initrd
fails to detect the CF card and leaves the system hanging at "Waiting for
root file system..." and after 30 seconds or so I am dropped onto a
rescue shell.
My first thought was that one or the other driver module needed for the
CF card was missing from the initrd, however after I rebuilt the initrd
with every single module that lsmod from the running system reports
included, it still is the same :(
When I do
$ cat /proc/modules
from the rescue shell, I can verify that
the modules are actually present, but
$ ls /dev | grep hd
shows that the device files for the CF card are still missing, so it is
no surprise that the file system is not found.
Shortly before the system hangs, the boot message
pcmcia_socket pcmcia_socket0: pccard: PCMCIA card inserted into slot 0
appears, and when I eject and re-insert the card, there are alike messages,
too, so apparently the slot itself is recognized, and even the card seems to
be detected somehow, but not recognized as compactflash card.
So it seems that there is some kind of "magic" missing from the initrd that
is responsible for probing the pcmcia port; I guess that the lines:
pcmcia_socket pcmcia_socket0: cs: memory probe 0xdfd00000-0xdfdfffff:
excluding 0xdfd00000-0xdfd0ffff 0xdfdf0000-0xdfdfffff
pcmcia 0.0: pcmcia: registering new device pcmcia0.0
from the dmesg output show that the card is finally detected, but
"who" is responsible for this (probably some udev rule? but how to set it up?),
and how to add this to the initrd?
I cannot believe that it is not possible to have the root file system on such
a card, but I have no idea what else to try.
Any ideas are much appreciated.
Below I attached some of the output of dmesg and lspci I get when I boot
into the working system on /dev/sda2, in case it might help to track
down the problem.
Regards and thanks in advance.
Michael
