Network is build around a 100 MB switch (D-LINK DES-1008D) with my computer placed on its own port. FTPserver also placed on its own port. Very low other traffic on the network. >Description: When sending a large file with FTP the vr interface hangs. I have tracked down the problem to the tx-part of the driver. The txstatus given in the ring descriptor have the value 0x00008800 when this happens. I have looked in the doc's for VIA Rhine chip and bit 0x800 is stated as 'reserved'. A fix by reinitialize the board when this bit is set seems to wake up the board again but the problem occurs soon after. I have also tried to turn off DMA for the disks, no success. I have tried to the patch given in kern/35720 without success (doesn't even seems to be called). >How-To-Repeat: Occurs every time I tries. >Fix: - >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
