I remember similar behavior with 4-STABLE around 4.6 time.
Proliant 3000 dual PIII + SmartArray:
1. runs fine on properly installed non SMP kernel
2. runs fine on properly installed SMP kernel
3. freezes during boot on mounting ida0 on non SMP kernel with SMP modules
and vice versa

It happend after installing SMP kernel that didn't boot. I booted
kernel.GENERIC and wasn't able to mount my ida volumes. Fortunately I had
system installed on regular SCSI disk, and restoring modules proper for
kernel I had booted helped.
