I spent some time testing kdump. I had to disable IOMMU to get kexec/kdump to work. Not sure why because neither the smartpqi driver nor our controllers care about IOMMU settings.
So, this perhaps is a platform issue.
I used the following kdump settings:
/etc/default/grub.d/kdump-tools.cfg
GRUB_CMDLINE_LINUX_DEFAULT="$GRUB_CMDLINE_LINUX_DEFAULT crashkernel=512M-:640M"
Not sure what all is really required, but kdump works with all of the above settings.

All of my other tests looked good.
fio performance testing - No regressions.
reboot testing
configuration testing - (using our SSA tools to switch between RAID and HBA mode)
