Hi, I've just installed -current on another one of my machines and have been seeing "usb0: 1 scheduling overruns" messages printed to the console over and over under load. As the load increases, so does the frequency of the messages. After a bit of experimenting, I've found that large amounts of network traffic (I used ftp) and bzip2'ing a large dump cause the message to be printed roughly ten times a second. This computer had been running -stable for a few months prior and did not exhibit this behavior. It's a dual Athlon MP 2000+ running on an Asus A7M-266D with an onboard AMD-brand OHCI USB controller. The only USB devices that are connected are a Microsoft Internet Keyboard Pro and an IntelliMouse Optical (1.0A). Unplugging both devices doesn't fix the problem. pciconf -lv thinks the following of the controller: ohci0_at_pci2:0:0: class=0x0c0310 card=0x80441043 chip=0x74491022 rev=0x07 hdr=0x00 vendor = 'Advanced Micro Devices (AMD)' device = 'AMD-768 USB Controller' class = serial bus subclass = USB usbdevs shows: addr 1: OHCI root hub, AMD addr 2: product 0x001c, Microsoft addr 3: Microsoft IntelliMouse® Optical, Microsoft The kernel config file and dmesg can be found at: http://siliconlandmark.com/staff/andre/files/BLING http://siliconlandmark.com/staff/andre/files/BLING.dmesg uname -a: FreeBSD bling.properkernel.com 5.0-CURRENT FreeBSD 5.0-CURRENT #1: Sun Apr 6 16:47:32 EDT 2003 root_at_bling.properkernel.com:/usr/src/sys/i386/compile/BLING i386 Any ideas?
