[syslinux] Invalid or corrupt kernel image

[Kosolapov Dmitry]

Hello again!
I've compliled new 2.6.16 Linux kernel with NFS root support (for
availability to mount root directory ftom the boot server). But after
pxelinux.cfg/default (it's configuration file) reading I get the error of:

Invalid or corrupt kernel image
boot:

The content of my pxelinux.cfg/default is:
LABEL linux
  KERNEL vmlinuz-2.6.16
  APPEND root=nfsd

I've even put initrd.img to tftpboot and wrote it down in
pxelinux.cfg/default, but problem seems to be not in it. I've copied my
system kernel (2.6.16 too) and tried to load it, it was loaded ok, but
dropped at the stage of mounting (Kernel panic..).
I've recompiled the kernel again, but no result. The problem seems not
to be in kernel, because the kernel doesn't even try to transfer to the
client machine and drops at once. What should I do? Thanks advance.
