/sbin/kexec became zero size... Anyone else?

[Jay Lan]

Hi,

My root disk was populated with sles10sp2, but the kernel was
2.6.27-rc5 and /sbin/kexec was built from 2.0.0 version.

Many times when kdump kernel failed early i found  after reboot that
/sbin/kexec became zero size. There was no warning on executing
'/etc/init.d/kdump start' when /sbin/kexec is zero size. I have
no idea when and how that happened.

Has anyone else seen this problem?

Thanks,
jay
