According to Santiago Garcia Mantinan:

This is a known erratum in 2.2.16. Here is a patch that reverts the
problematic RAID change:

Index: drivers/block/md.c
*************** static int do_md_run (int minor, int rep
*** 447,452 ****
factor = min = 1 << FACTOR_SHIFT(FACTOR((md_dev+minor)));
- md_blocksizes[minor] <<= FACTOR_SHIFT(FACTOR((md_dev+minor)));
-
for (i=0; i<md_dev[minor].nb_dev; i++)
if (md_dev[minor].devices[i].size<min)
--- 447,450 ----
