Message-ID: <mksia9$u5b$1@ger.gmane.org> Date: Fri, 5 Jun 2015 13:21:26 -0300 From: Dâniel Fraga <fragabr@...il.com> To: linux-kernel@...r.kernel.org Subject: 4.0.4 kernel BUG at lib/radix-tree.c:461 (with Call Trace) I posted the following Call Trace at Kernel bugzilla, but nobody replied so I'm posting here. This is not reproducible. It happened when watching a Youtube video. https://bugzilla.kernel.org/show_bug.cgi?id=99441 My system stalled (no keyboard, no mouse) and I got this: Jun 5 00:41:00 tux kernel: [427295.519312] ------------[ cut here ]------------ Jun 5 00:41:00 tux kernel: [427295.519332] kernel BUG at lib/radix-tree.c:461!
