I have root prepared on /dev/mmcblk0p6. I tried 3.17 with
rx51_defconfig, but no, it refuses to mount it.

VFS: Cannot open root device "mmcblk0p6" or ....: error -19.

And then it proceeds to list mmcblk0p6 as one of available
options

:-(.

Ideas welcome.

Try to add rootdelay=30 or rootwait to kernel cmdline.

I had rootdelay=3. Will try rootwait... no change. This is v3.17 with
rx51_defconfig. CONFIG_MACH_NOKIA_RX51=y => device tree will not be
used AFAICT.

Now I'm back at 3.14 without device tree; same setup works there. I
tried disabling RX51 support in 3.14 (to make it boot using device
tree) but that did not work.
