I too have current (as of last week), newbus, and sio as well as pcm0 I see heaps of lost interrupts. The mail archive has one message saying "newbus broke fast interrupts' but no (not much?) followup to clarify (a) if its still true and (b) what exactly it implies for finding which driver is stealing the interrupt cycle time and causing byteloss on the serial ports. Can somebody provide a canonical answer to why for some people the serial driver performance is off right now? cheers -George To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
