Subject: i.MX28 nand driver broken in Linux 4.18
Date: Fri, 8 Feb 2019 10:27:19 +0100	[thread overview]
Message-ID: <8ec3f0b1-b288-d208-c0e4-431b49719d08@grandegger.com> (raw)

Hello,

I'm upgrading the BSP of my i.MX28 board to Linux 4.18. Unfortunately,
the NAND driver does not working any longer. Here is the output of
"nandtest" including the kernel messages:

I have already applied the patch: 

  [PATCH] mtd: rawnand: gpmi: fix MX28 bus master lockup problem

but it didn't help. It works fine with Linux 4.14. Are there any known
issues with 4.18?

Thanks,

Wolfgang.
