Dec  8 02:38:07 evil /kernel: cy15: 1 more silo overflow (total 3897)

This has crept in sometime during the past few days. Previously cy.c
would suffer silo overflows far more rarely (once every 10-30 seconds
on average) and overflows quantities were never over 2 or 3.

Response time generally has suffered, even with a very low load. Feels
like some kind of excessive context switching delay.
