Subject: [Powerpc] Sam460ex Canyonlands issue -Kernel 4.4.6-rc1
Date: Mon, 28 Mar 2016 19:47:49 -0400 [thread overview]

Hi
Seeing the following when booting kernel 4.6-rc1 on Acube Sam460ex Canyonlands board.
This loops for a few times then the kernel boots.
No problem with the 4.6-rc1 with an A-eon Tabor Freescale e500v2 board.
Regards
Julian
