Oh.. wait... I've missed that DNS-313 doesn't have any onboard flash and 
boots from hdd!
Seems we need CONFIG_JBD2=y and CONFIG_FS_MBCACHE=y (along with ext4 and 
other fs) back.

No, I don't have the same, Raidsonic (and other boards, afaik) have 
onboard flash which can be used for system.
So hard drives can be used for pure storage, which is more convenient, 
IMO.

Could be... what does dmesg say about that? does it read any phy_id ?
Raidsonic has Marvell 88e1116 phy but works as generic phy just fine:

[    5.731760] Generic PHY gpio-0:01: attached PHY driver [Generic PHY] 
(mii_bus:phy_addr=gpio-0:01, irq=POLL)
[    5.731781] phy_id=0x01410e11, phy_mode=rgmii
