Subject: Domain faults when CONFIG_CPU_SW_DOMAIN_PAN is enabled
Date: Thu, 3 Dec 2015 07:43:11 +0000	[thread overview]
Message-ID: <6ae83861a7c8436d983ef99cd1b48a76@EMAIL.axentia.se> (raw)

Hi!

If I enable CONFIG_CPU_SW_DOMAIN_PAN, I sometimes (but not always) get the
following (or very similar) on boot.

Cheers,
Peter
