Observed tcpdumps - missed packet with retransmit timeout although no TCP/IP errors were shown on netstat. NIC LEDs paused many times for approx 1 sec. During debug of if_ed.c (printfs, DMA status tests, etc.), noticed wd0 DMA errors???? Couldn't do anything to appreciably improve performance - any time I did, got wd0 DMA errors. >How-To-Repeat: See above. >Fix: Enable PCI, DMA, etc. flags on wdc0 controller ala: controller wdc0 at isa? port "IO_WD1" bio irq 14 flags 0x00ffa004 vector wdintr This cleared up the problem. Now ftp rx at 1.07 MB/s. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
