Problems when boot new kernel 2.5.66 kernel panic

[jds]

Hi my name is Jesus Delgado from Mexico City:

  I need help for resolve this problems, compile kernel 2.5.66 in rh 8, update
my lvm to lvm2 utils, devmapper, modutil 2.4.24, when try to boot with new
kernel recive this messages:

   VFS: Cannot open root device "rootvg/lvol1" or unknown-block(0,0)
   Please append a coorect "root=" boot option
   kernel panic
   VFS= Unable to mount fs on unknown-block(0,0).

   In my new kernel the modules this into kernel not how modules.


   In kernel 2.4.20 the boot OK with LVM

I've exactly the the same Problem here, Kernel 2.5.66, no modules, no raid,
no lvm, tried with devfs and without it

	VFS:  Cannot open root device "301" or ide(3,1) <-- this IS my /dev/hda1
	kernel panic

- sys_mknod in mount_root for device 301 succeeds, but
- sys_mount in do_mount_root returns ENOENT for "/dev/root"

Kernel 2.5.65 compiled with the same Config-Options and the same compiler boots
correctly.

Any Suggestions ?

	Norbert

I think you have the old modutils unless Rusty changed the version numbers
drastically. From memory they are somewhere in
  ftp:ftp.kernel.org/pub/linux/kernel/people/rusty

However, your problem *might* be initrd if the drivers are not all built
in. The stock Redhat mkinitrd called by "make install" doesn't seem to
work, and Rusty has stated he has no intentions of providing a working
one. I'm told there's a new mkinitrd at Redhat, but I haven't found it (or
even looked very hard).

If you are building it all in I can't help.

Hi Jesus !

I have tried to hunt down our problem a lot of hours, but without Success.

Neither the bk-patches nor the mm-patches cure the panic, i've tried 3
different compilers and two binutils.

The strangest thing about this is that we seem to be the only people triggering
the bug, as there is no echo in the LKML.

I give up and go back to 2.5.65 :-(

Below some debugging statements, if there should be somewhere outside
who likes to spent his time in frustrating debugging Sessions ...

Bye
    Norbert
