I tried to update Filesystem type (from 42 SFS to 83), which messed one of the disks (luckily) and had to rebuild the RAID.. post which I found that this specific issue is now gone. I can mount fine on any kernel version..
Please feel free to close this.. I hope this help someone who is facing this issue or faces this in future..
