The following reply was made to PR arm/158950; it has been noted by GNATS. From: Kristof Provost <kristof@sigsegv.be> To: bug-followup@FreeBSD.org Cc: Subject: arm/158950: arm/sheevaplug fails fsx when mmap operations are enabled Date: Mon, 7 May 2012 14:15:51 +0200 Based on a suggestion from Ian Lepore I switched the data cache from write-back to write-through mode. In that case the problem doesn't occur. Ian suggested this might indicate a problem in the busdma cacheline flush code, but unfortunately I'm somewhat out of my depth there.
