I have on-board 1GiG network card: em0@pci0:0:25:0: class=0x020000 card=0x82681043 chip=0x10bd8086 rev=0x02 hdr=0x00 vendor = 'Intel Corporation' device = '82566DM-2 Gigabit Network Connection' class = network subclass = ethernet I have jumboframes enabled: em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 9014 It works perfectly on large voulme transfers: copy 8GiB file va NFS or SMB works Ok in both direction. But when I try to run `kdeinit4' on this computer with DISPLAY points to other computer (my desktop), I get 2-3: em0: watchdog timeout -- resetting em0: link state changed to DOWN em0: link state changed to UP I found, that some chips should be reflashed with new EEPROM, but not this one. Is here any solution? uname -a FreeBSD xxx.xxx.xxx 7.1-PRERELEASE FreeBSD 7.1-PRERELEASE #0: Sat Aug 30 23:42:02 MSD 2008 lev@xxx.xxx.xxx:/usr/home/storage/obj/usr/src/sys/BLOB amd64 -- // Lev Serebryakov
