Am seeing some DMAR error messages on reboot after a 'shutdown -r now'.
(Finally got annoyed enough to track it down while doing a git bisect)
Hardware: Dell Latitude E6530 laptop.
Working (booting from power-off state):

This is probably from a missing RMRR entry for device 00:1f.2. Can you
please post full dmesg after boot?
Thanks,

lspci says:
00:1f.2 SATA controller: Intel Corporation 7 Series Chipset Family 6-port SATA Controller [AHCI mode] (rev 04)
Not sure why I only see it on reboots - that means that when powering up, the kernel
gets handed a device config it likes, but when rebooting, something is leaving the
device in a config the kernel doesn't want to see.
Cold and warm boot dmesg's attached.

Okay, so the BIOS defines one RMRR entry:
DMAR: RMRR base: 0x000000cdb11000 end: 0x000000cdb30fff
But the device-scope doesn't seem to match any existing devices in your
system. At least no device gets the RMRR mappings later on.
That doesn't really matter, as the the fault-address of 0xcdacd000 is
outside of the defined RMRR range anyway.
Looking at the fault-address as system physical, is would be in this
range of system memory:
BIOS-e820: [mem 0x00000000cd99b000-0x00000000ce3a0fff] reserved
Which is reserved for BIOS use. This looks very much like a missing RMRR
entry for that range, that has the sata controler in its device scope.
