[BUG BISECT] Net boot fails on VF50 after "dmaengine: fsl-edma: support little endian for edma driver"
From: Krzysztof KozÅowski
Date: Tue Jul 02 2019 - 08:12:59 EST
Hi,
Bisect pointed commit:
commit 002905eca5bedab08bafd9e325bbbb41670c7712
Author: Peng Ma <peng.ma@xxxxxxx>
Date: Thu Jun 13 10:27:08 2019 +0000
dmaengine: fsl-edma: support little endian for edma driver
as a reason of NFSv4 root boot failures. Toradex Colibri VF50 (Cortex
A5) on Toradex Iris board.
The user-space starts but hangs - a lot of messages are missing or
seriously delayed.
Please revert the patch of fix it. If needed I can provide more
details about test system - let me know.
Full log attached.
Best regards,
Krzysztof
