Here is some more info: I loaded the module with option core_debug=15. When I run with low CPU load (vx driver), I get the following log lines: [10261.346087] tw6804[0]: tw68_buffer_queue: queuing buffer cd7bb3c0 [10261.346087] tw6804[0]: tw68_buffer_queue: [cd7bb3c0/0] first active [10261.346087] tw6804[0]: tw68_buffer_queue: queuing buffer cc91b260 [10261.346087] tw6804[0]: tw68_buffer_queue: [cc91b260/1] appended to active [10261.393852] tw6804[0]: tw68_wakeup: [cd7bb3c0/0] field_count=293 [10261.397831] tw6804[0]: tw68_buffer_queue: queuing buffer cd7bb3c0 [10261.397831] tw6804[0]: tw68_buffer_queue: [cd7bb3c0/0] appended to active [10261.433849] tw6804[0]: tw68_wakeup: [cc91b260/1] field_count=294 [10261.437823] tw6804[0]: tw68_buffer_queue: queuing buffer cc91b260 [10261.437823] tw6804[0]: tw68_buffer_queue: [cc91b260/1] appended to active [10261.473839] tw6804[0]: tw68_wakeup: [cd7bb3c0/0] field_count=295 [10261.477415] tw6804[0]: tw68_buffer_queue: queuing buffer cd7bb3c0 [10261.477415] tw6804[0]: tw68_buffer_queue: [cd7bb3c0/0] appended to active [10261.511590] tw6804[0]: tw68_wakeup: [cc91b260/1] field_count=296 [10261.518421] tw6804[0]: tw68_buffer_queue: queuing buffer cc91b260 [10261.518421] tw6804[0]: tw68_buffer_queue: [cc91b260/1] appended to active [10261.552610] tw6804[0]: tw68_wakeup: [cd7bb3c0/0] field_count=297 [10261.577131] tw6804[0]: tw68_buffer_queue: queuing buffer cd7bb3c0 [10261.577158] tw6804[0]: tw68_buffer_queue: [cd7bb3c0/0] appended to active [10261.593610] tw6804[0]: tw68_wakeup: [cc91b260/1] field_count=298 [10261.599735] tw6804[0]: tw68_buffer_queue: queuing buffer cc91b260 [10261.599759] tw6804[0]: tw68_buffer_queue: [cc91b260/1] appended to active [10261.633812] tw6804[0]: tw68_wakeup: [cd7bb3c0/0] field_count=299 [10261.637784] tw6804[0]: tw68_buffer_queue: queuing buffer cd7bb3c0 [10261.637784] tw6804[0]: tw68_buffer_queue: [cd7bb3c0/0] appended to active [10261.673804] tw6804[0]: tw68_wakeup: [cc91b260/1] field_count=300 [10261.677776] tw6804[0]: tw68_buffer_queue: queuing buffer cc91b260 [10261.677776] tw6804[0]: tw68_buffer_queue: [cc91b260/1] appended to active Very regular, just one "first active".
