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.
