Flash drive problems after WoL

Hi,

I've been trying to get WoL to work reliably under unRAID for nearly two years now.  I recently tried sending my unRAID box to sleep via the Dynamix S3 Sleep plugin, waking it using 'rtcwake' (see https://forums.lime-technology.com/topic/58194-scheduled-wake-from-sleep/), which appeared to work, but after waking there was no 'Docker' tab or apps and the system was in a rather confused state.  Clicking on the 'Log' button, I got the following immediately after the wake-from-sleep:

This is characteristic of the sleep issues that have plagued my unRAID experience.  Has anyone else had this problem and found a solution?
