Since the iOS 12 update, I've noticed two entries being entered frequently to the diagnostic data logs: "backboardd.wakeups_resources" and "SpringBoard.wakeups_resources". I was wondering if this is an issue with an iPad or if this is a side effect of iOS 12, For reference, my device is a 10.5 inch iPad Pro purchased in May. Any advice would be greatly appreciated!
iPad Pro Wi-Fi, iOS 11.4
Hi.
Came across your question while looking for information on the backboardd.wakeups_resources entries in the diagnostic logs. I have also been noticing these entries, am using an iPad Pro running iOS 12.0. Below is what the latest backboardd.wakeups_resources entry in my diagnostic logs says:
{"app_name":"backboardd","app_version":"","bug_type":"142","timestamp":"2018-10- 18 21:11:40.88 +0100","os_version":"iPhone OS 12.0 (16A366)","incident_id":"5CE4CA80-C5ED-4560-9449-31F46F85F122","slice_uuid":"7D 9FFF3C-AAF1-32DF-A1F8-8404FE333C28","build_version":"","is_first_party":true,"sh are_with_app_devs":true,"name":"backboardd"}

I cannot offer any advice as to the above's meaning or cause but thought you might like to know that I'm also experiencing the above using the same hardware/operating system version as yourself.
