Nose was opened and DSM 305 was dried as much as possible prior to powering ON.
ADS server did not startup in fully operational state. Swapped to Spare ADS server @ 1140.
DSMs 304 and 305 did not boot. These are not necessary for research so takeoff was not delayed.
1245 - Cycled power on 10um 2D. No effect. Came back on its own several minutes later. Exhibits the same behavior during ascent as in previous flights.
1309 - Cycled VCSEL. Data came back... DPR did not track VCSEL well.
1315 - Cycled NOSE/MPDB Control Switch. Chris eventually found that DSMs 304 and 305 were in a continuous reboot state and he was able to fix them. They remained stable for the remainder of the flight.
PSTF was -32767; may have been effected by moisture in the Nose when power was applied.
CAVP_DPL and CAVP_DPR had very large offset from one another. At 40K+ feet, CAVP_DPL -47 hPa; CAVP_DPR 364 hPa (neither are reasonable values)
No DP_DPL display on AEROS
QCTF had large offset from QCF/QCR
Large RTH1/RTH2 offset due to A/D card 1706 swap into DSM 305.
Had a hard time getting Catalog Maps displayed on the plane due to server swap.
Re: dsm304 and dsm305 in some sort of auto boot mode. After about half our ascent they seemed to calm down and stay running. No real explanation for this at this time. Possibly after I succeeded to log into them between reboots, so maybe ssh'ing updated known_host or ssh keys.

Lost both 2D probes during descent.

There were definitely issues with the top of fuselage readings, but they seemed to come back for RF19 (plus are not critical for our wind estimates).
