[arch-general] efibootmgr doesn't change boot order!

I read an forum entry from nearly 6 years ago about am efibootmgr bug that Doesn't let you change the boot order on a multi OS system if you have arch linux as the default OS. Had some users report this as well in other forums. Now i am facing the that problem in my system with arch ubuntu and windows. when i change the boot order , it shows the change 'temporarily' but when i restart it boots the default (Arch linux Grub ) and the change disappears. I faced this issue last month and gave up on it since I couldn't find any detailed resource on this on the net. This list may be my last hope. If anybody could give some direction , would be much appreciated. regards, khaithang39
