Hi :) What's the state of this? I have this issue on a number of EC2 instances that are using bcache to speed up EBS access by caching on the ephemeral SSDs (writethrough mode). "echo 0 > /sys/block/bcache0/bcache/writeback_running" as suggested by others stops the flood of "blocked" messages in dmesg, but it only partly fixes the 2.0 minimum load average issue (instead, it's now a 1.0 minimum load average). I just tried the latest kernel I could get my hands on for Ubuntu Trusty, the mainline v3.15-rc2 (built April 20th), and it exhibits the same behavior. Thanks :) Daniel -- To unsubscribe from this list: send the line "unsubscribe linux-bcache" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
