Strange ATA status error (SETFEATURES. ACB ? )
Quick recap: this is on an alix2d13 with 256mb of ram, a new SanDisk CF 8gb card, and no other added peripherals (no minipci, no usb, no ide) that is crashing constantly (roughly 30-75min between crashes). The CF card was bought a few days ago, but the alix2d13 and power supply were bought in the beginning of 2014, but I haven't had time to try setting it up until now.
I thought the ATA controller just managed the IDE port, but looking at the boot messages, it appears that the CF card is also attached to ata0:

Later on in the serial console output (still while booting, just before the pfsense console menu), this error pops up:
2015/08/13 17:31:51 PDT : (pass0:ata0:0:0:0): SETFEATURES.

Anyone know what that's about?
PS, if it helps, here is a pastebin of the serial console output from a full boot->crash cycle: http://pastebin.com/Y0KHza54
(I removed the ipv6 ip listed in the pfsense menu, but let me know if there is anything else I should have redacted).
All the lines are preceded by a timestamp by a script I wrote that is logging the serial console and creating a new log each time it sees the "PC Engines ALIX.2 v0.99m" boot banner.
Googled and found this freebsd thread: https://forums.freebsd.org/threads/camcontrol-error-sending-command.35548/
It turns out to just be an error from attempting to disable APM on the card (which is denoted by the first line before and after the error).
My first thought was that the card didn't support APM, but I ssh'd in and used camcontrol identify on ada0 and the card does indeed support APM:

Perhaps because APM is already disabled?
In any case, it's a red herring and not related to my hourly crashes at all.
