kexec on panic

[Denys Fedoryshchenko]

Hello,

After years of using kexec and recent unpleasant experience with modern 
(supposed to be blazing fast to boot) hardware that need 5-10 minutes 
just to pass POST tests,
one question came up to me:
Is it possible anyhow to execute regular (not special "panic" one to 
capture crash data) kexec on panic to reduce reboot time?

Thanks!
