|I had a WRT1900ACSv2 a few months ago that had worked perfectly for six months or so on dd-wrt January 2019 build 38159 that one day suddenly decided to boot into the original Linksys firmware on the other partition. The triple-power-cycle maneuver from the Cliff Notes (top of the Marvell forum) got it back into dd-wrt. Something made me suspect the CPU temp was the issue, so I set it on a USB fan blowing upward through the case. The problem has not recurred.
I don't really recall what made me suspect temperature. The router was operating in a southern California summer setting in a house with nonaggressive A/C, so the room was warm for sure, and perhaps the CPU temp on the GUI's Status page was actually 75C or higher? I just don't remember. I may have just assumed that was the issue because I had seen other routers of that model get squirrely when a bit hot.
I used the AC Infinity 120mm fan. It was US$12 or so and had rubber feet to keep things from rattling or scratching. I think I bought it from Amazon or NewEgg. At this point I have six identical routers on that same model fan. Only one other router from that set had obvious temperature problems, obvious but different ones in that case that clearly went away and stayed away once the router was on a fan, but at some point it seemed wise to just head off trouble with the others rather than risk user wrath and/or inconvenience.
Six of the Linksys WRT1900ACSv2 on r38159 (solid), r39144 (very solid), r40009 (solid), and r40784 (trying out). On various:
VLANs, client-mode travel router, two DNSCrypt servers (incl Quad9), multiple VAPs, USB/NAS, QoS, OpenVPN client/PBR (random NordVPN server).
