Freeing unused kernel memory: 56k init

[srinivas.surabhi at wipro.com]

When I tried to debug for the reason of  "Freeing unused kernel memory:
56k init " hang problem  the following is the printk outputs...

Entering kernel_read



Entering elf_map



map_addr was 0x30026000 



Failed due to bad address



Entering padzero



...



>From the above can anything be concluded ?



One more doubt was, is it mandatory that the Virtual memory has to
enabled while building the Mounta Vista linux kernel ? Why because there
was an option to enable the kernel base address and if it is enabled it
asks for what is the address for the Kernel Virtual base address? If I
give 0x0 it works otherwise the Kernel itself is not at all booting.



Till the statement "Freeing unused kernel memory: 56k init"  is coming
only if and if the 0x0 was given for the kernel virtual base address.





Thanks & Regards

The latest update is that the init was also found in one of the
packages. So now I am not facing init not found problem . But there was
a hung problem, once the init is invoked .. Please find the output
below...



RAMDISK: Compressed image found at block 0

Freeing initrd memory: 1235k freed

kjournald starting. Commit interval 5 seconds

EXT3-fs: mounted filesystem with ordered data mode.

VFS: Mounted root (ext3 filesystem) readonly.

Mounted devfs on /dev

Freeing unused kernel memory: 56k init

< there is no output after the above statement.....>

Thanks & Regards

Fine. So you can mount the root filesystem, but it obviously does not
contain all the required files.

No. /etc/fstab has absolutley nothing to do with  your  problem.  The
kernel  cannot  start  the  init  porocess - make sure init is in the
filesystem, plus all required libraries.

filesystem

This is completley unrelated.

Please contact MV support. I have no  idea  how  they  package  their
distribution,  or  how  their  config  tools might work. You paid for
their stuff, so ask _them_.
