This is on a Dell Poweredge 2650 with dual Xeons. Running Gentoo x86.
Kernel 3.18.7 with GRSecurity patches (gentoo's hardened-sources).
btrfs-progs version 3.18.2
I originally had the drives setup as raid5 with kernel 3.19 and no
GRSecurity patches (and tried 4.0-rc1)., but kept having these issues so
I balanced the system to raid10 and this did not help. That's when I
switched to 3.18.7 kernel as it's been running fine on all of my x86_64
Gentoo systems in various raid1, 5, and single arrays.
This is the trace I get in dmesg whenever I try to run rsync from the
local server or remote server that touches any Btrfs filesystem:

The filesystem is on 4 SCSI drives and encrypted using LUKS/dm-crypt.
Never had any issues before with the encryption, so I don't think that's
the issue.

Any ideas to solve this? What other information will help?
