[REGRESSION next-20170426] Commit 09515ef5ddad ("of/acpi: Configure dma operations at probe time for platform/amba/pci bus devices") causes oops in mvneta
From: Ralph Sennhauser
Date: Wed Apr 26 2017 - 12:15:43 EST
Hi Sricharan R,
Commit 09515ef5ddad ("of/acpi: Configure dma operations at probe time
for platform/amba/pci bus devices") causes a kernel panic as in the log
below on an armada-385. Reverting the commit fixes the issue.
Regards
Ralph
