According to the info I have, the problem appeared after a routine
update to the navigation database in the FMC, provided by Honeywell.
The update resulted in the FMC being unable to compute performance
parameters such as takeoff speeds.

After determining that none of the updates were relevant to routes
flown by United, FAA permission was received to temporarily revert to
the previous month's version of the database.

Delays of up to two hours were reported, and one flight diverted.
