While trying to compile www/chromium on a Pi3 running r354909
the system reported a panic which is new, at least to me:
panic: data pending interrupt pushed through SDHCI framework

suggesting the panic happened while vmstat was writing to the log.
For the moment I'll update /usr/src and rebuild. Please indicate if more useful
