Kernel Errors in Syslog

[Hoopster]

The following kernel errors just showed up in my syslog (note:  I am currently running preclear on two 3TB WD Red drives - the preclear on both continues to run with no problems):

Are these errors cause for concern at this point?  To my knowledge, these errors have never before appeared in the syslog.  They look CPU cache related.

[Hoopster]

Hmm, I am running a second preclear cycle on the same disks and the kernel errors just appeared again.  Doesn't seem to affect the preclear, but, this has happened twice now and only while running preclear - always during the zeroing disk phase.

Hey Hoopster, I am seeing the same error messages. Doing my initial Preclear on Three 3TB WD Red drives, and when it got to about 20% on the zeroing phase I saw these errors. it is still running fine though. How did your Preclear turn out?
