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!
