Kexec and rt kernel

Hi All,
Although it does not have an upmost priority for me, there is an issue that i would like to report. 
 
Last week, I tried to use kexec with RT kernel (2.6.23 - rt3) but i was not successful. The problem is that RT kernel does not boot up from the host kernel. It loads successfully but it freezes during boot up at some point. 
 
After seeing this behavior, i made the following tests. 
 
- I used 2.6.19 vanilla kernel as host kernel and was able to boot up the same 2.6.19 kernel with kexec.
- I used 2.6.19 vanilla kernel as host kernel and was able to boot up 2.6.23-rt3 with kexec
 
with 2.6.23-rt3 as host kernel both 2.6.19 and 2.6.23-rt3 does not start up.
 
for your information,
