Subject: Kernel lockup: "fs/btrfs/delayed-inoce.c:1410 btrfs_assert_delayed_root_empty"
Date: Mon, 01 Dec 2014 19:24:30 -0200 [thread overview]
Message-ID: <m5imaf$s9b$1@ger.gmane.org> (raw)
Hi,
I'm having fairly frequent kernel lockups caused by btrfs, which I think
it might be a serious bug. I'm using linux-3.17.3.200.fc20.x86_64. It
freezes the whole system, and spits the error trace in the journal a few
seconds later.
Here's the journal log, notice that there are 2 stack traces with little
time between them:
