Hi,
On today's next, the bisect pointed commit
ff33d1030a6ca87cea9a41e1a2ea7750a781ab3d as fault for my boot failures
with NFSv4 root on Toradex Colibri VF50 (Iris carrier board).

OF: Don't set default coherent DMA mask
Board: Toradex Colibri VF50 (NXP VF500, Cortex A5, serial configured
with DMA) on Iris Carrier.
It looks like problem with Freescale Ethernet driver:
[ 15.458477] fsl-edma 40018000.dma-controller: coherent DMA mask is unset
[ 15.465284] fsl-lpuart 40027000.serial: Cannot prepare cyclic DMA
[ 15.472086] Root-NFS: no NFS server address
[ 15.476359] VFS: Unable to mount root fs via NFS, trying floppy.
[ 15.484228] VFS: Cannot open root device "nfs" or
unknown-block(2,0): error -6
[ 15.491664] Please append a correct "root=" boot option; here are
the available partitions:
[ 15.500188] 0100 16384 ram0
[ 15.500200] (driver?)
[ 15.506406] Kernel panic - not syncing: VFS: Unable to mount root
fs on unknown-block(2,0)
[ 15.514747] ---[ end Kernel panic - not syncing: VFS: Unable to
mount root fs on unknown-block(2,0) ]---
Attached - defconfig and full boot log.
Any hints?
Let me know if you need any more information.
Best regards,
Krzysztof
