This is causing the following trace every second or 2 on my laptop:

Of course backing it out makes the messages go away, since dm_any_congested() was added by that patch. This patch just not ready for prime time, or am I (as usual) managing to trip over some silly corner case due to odd configuration? [unhandled content-type:application/pgp-signature] | |
