Hi! While with 3.16-rc3 and rc4 I didn´t have a BTRFS hang in several days of usage, with 3-16-rc5 I had a hang again. Less than a hour since booting it. Since the hang bug I and others had with 3.15 and upto 3.16-rc2 usually didn´t happen that quickly after boot and since backtrace looks a bit different from what I have in memory, I post this in a new thread. See thread "Blocked tasks on 3.15.1" for a discussion of previous hang issues. I lost a mail I was about to send with kmail. merkaba:/boot> ps aux | grep D USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 162 0.0 0.0 0 0 ?
