PCI problem
From: <hidden>

Hi, We are facing the problem with MVlinux3.1 having kernel 2.4.20 booting once the PCI is enabled in config kernel. First Question is it any where required in linux kernel sources to make the PCI configuration changes...IF so please let me know in which file ?? Even the message "linux kernel banner " which is at the beginning of the start_kernel function is not seen. Once the multi image( kernel + ram disk File system) is extracted into RAM. After that it hangs bootm 0xfef80000 ## Booting image at fef80000 ... Image Name: MultiImage Image Type: PowerPC Linux Multi-File Image (gzip compressed) Data Size: 4647626 Bytes =3D 4.4 MB Load Address: 00000000 Entry Point: 00000000 Contents: Image 0: 551181 Bytes =3D 538.3 kB Image 1: 4096430 Bytes =3D 3.9 MB Verifying Checksum ... OK Uncompressing Multi-File Image ... =3D0=3D OK Booting Linux Loading Ramdisk to 07417000, end 077ff1ae ... OK ...Then hangs .... SO please help me out in finding out the relation of PCI and the start_kernel. As per my knowledge once the kernel_init is entered then the pci_init is invoked. But strangely I am seeing with pci enabled, hang at the very beginning..

So
edited the filesytem parameter for / as /dev/ram earlier it used to
be
/dev/root.
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.
So please tell me whether the given fstab file will suffice? The
filesystem This is completley unrelated.
2. I have one more doubt /sbin/init utility comes with what package? Because in /sbin directory although the init binary is present, not

in the file system heirarchy view. For eg. if I select DHCPD package
then
able to see dhcpd related binary in the /sbin similarly my question
was
which package has to be selected to have init included.
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_.
