Contrary to expectations, my experience with this patch on a 2.6.18-rc4 kernel is that kexec -l, kexec -e is now working without my adding any delays to mptscsih, and the kexec -p, echo c >/proc/sysrq-trigger case hangs. My "got here" printk's on the console indicate: SysRq : Trigger a crashdump machine_crash_shutdown device_shootdown machine_kexec type: 1 And then it hangs.
