input/output errors on btrfs-luks-lvm

Hello,

I'm running kernel 4.3.3-2-ARCH, and I sometimes get 'Input/output error' when trying to access files.

I haven't found any logs as to why, and nothing appears in dmesg.

I'm running in a subvolume on an encrypted fs running on lvm.

I've tried a scrub, which has worked before , but no luck. I could try a reboot, but I wanted to see if there's any other suggestions first.
