6.10.3 BUG: Bad page map in process preclear_disk.s

[boxtor]

I was  preclearing a HDD at 95% of the zero'ing, when the UI became partially responsive.  The dashboard wasn't updating properly and the Unassigned Devices widget on the main screen failed to refresh.  I noticed the following in my logs and I'm wondering if I have a non-HDD component failing.  I haven't tried any version before 6.10.3, since it's the first version I have installed recently.

 

Eventually the UI started responding correctly.
