At the moment they are being operated in 10BaseT mode, and have -link2 for ifconfig specified in sysconfig. On two of the machines, the cards work fine, but on the other two, when *receiving* data, there are delays every so often of around 1 second, the frequency of which varies, giving transfer rates of anything between 10k/s, and 500k/s. In all cases data is written (other than to the other slow machine) at just over 1Mb/s. Reading and writing to another machine running 2.1.5R with a 3C509 produced the same results, and the problem seems to be machine rather than card dependant, as I've tried swapping the cards. `ifconfig de0' shows the following: de0: flags=8863 mtu 1500 inet 194.125.135.250 netmask 0xffffffc0 broadcast 194.125.135.255 and the boot sequence is as follows: Oct 10 00:29:29 gate-uk /kernel: FreeBSD 2.1.5-RELEASE #0: Wed Oct 2 16:23:01 B ST 1996 Oct 10 00:29:29 gate-uk /kernel: root@gate1.acucobol.ie:/usr/src/sys/compile /GATE Oct 10 00:29:29 gate-uk /kernel: CPU: 134-MHz Pentium 735\90 or 815\100 (Pentium -class CPU) Oct 10 00:29:29 gate-uk /kernel: Origin = "GenuineIntel" Id = 0x52c Stepping =12 Oct 10 00:29:29 gate-uk /kernel: Features=0x1bf Oct 10 00:29:29 gate-uk /kernel: real memory = 16777216 (16384K bytes) Oct 10 00:29:29 gate-uk /kernel: avail memory = 15122432 (14768K bytes) Oct 10 00:29:29 gate-uk /kernel: Probing for devices on PCI bus 0: Oct 10 00:29:29 gate-uk /kernel: chip0 rev 1 on pci0:0 Oct 10 00:29:29 gate-uk /kernel: chip1 rev 1 on pci 0:7:0 Oct 10 00:29:29 gate-uk /kernel: chip2 r ev 0 on pci0:7:1 Oct 10 00:29:29 gate-uk /kernel: vga0 rev 84 int a irq 9 on pci0:17 Oct 10 00:29:29 gate-uk /kernel: ahc0 rev 3 int a irq 12 on pci0:18 Oct 10 00:29:29 gate-uk /kernel: ahc0: aic7870 Single Channel, SCSI Id=7, 16 SCB s Oct 10 00:29:29 gate-uk /kernel: ahc0 waiting for scsi devices to settle Oct 10 00:29:30 gate-uk /kernel: (ahc0:0:0): "Quantum XP32150W L912" type 0 fixe d SCSI 2 Oct 10 00:29:30 gate-uk /kernel: sd0(ahc0:0:0): Direct-Access 2151MB (4406960 51 2 byte sectors) Oct 10 00:29:30 gate-uk /kernel: de0 rev 18 int a irq 5 on pci0:20 Oct 10 00:29:30 gate-uk /kernel: de0: DC21140 [10-100Mb/s] pass 1.2 Ethernet add ress 00:00:c0:9a:d2:e4 Oct 10 00:29:30 gate-uk /kernel: de0: enabling 10baseT UTP port Oct 10 00:29:30 gate-uk /kernel: Probing for devices on the ISA bus: Oct 10 00:29:30 gate-uk /kernel: sc0 at 0x60-0x6f irq 1 on motherboard Oct 10 00:29:30 gate-uk /kernel: sc0: VGA color <16 virtual consoles, flags=0x0> Oct 10 00:29:30 gate-uk /kernel: sio0 at 0x3f8-0x3ff irq 4 on isa Oct 10 00:29:30 gate-uk /kernel: sio0: type 16550A Oct 10 00:29:30 gate-uk /kernel: sio1 at 0x2f8-0x2ff irq 3 on isa Oct 10 00:29:30 gate-uk /kernel: sio1: type 16550A Oct 10 00:29:30 gate-uk /kernel: lpt0 at 0x378-0x37f irq 7 on isa Oct 10 00:29:30 gate-uk /kernel: lpt0: Interrupt-driven port Oct 10 00:29:30 gate-uk /kernel: lp0: TCP/IP capable interface Oct 10 00:29:30 gate-uk /kernel: fdc0 at 0x3f0-0x3f7 irq 6 drq 2 on isa Oct 10 00:29:31 gate-uk /kernel: fdc0: NEC 765 Oct 10 00:29:31 gate-uk /kernel: fd0: 1.44MB 3.5in Oct 10 00:29:31 gate-uk /kernel: npx0 on motherboard Oct 10 00:29:31 gate-uk /kernel: npx0: INT 16 interface Has anybody come across this before, or have any ideas.
