Intel Pro/1000 MT troubles (revised) 2004-11-26 - By Jos Vos
Back
Hi,
In my last posting about the Intel Pro/1000 MT 4-port card I said
the problem was "solved " by disabling the USB controller in the BIOS.
This appears to be not true (it was an observation made by someone
testing it remotely): the symptoms were less problematic - no kernel
hangs - but only 1 of the 4 ports actually worked, the rest could
send packats, but never saw any packet coming in (IRQ problem, I
guess...).
Then I tried a SMP kernel on this (non-HT-capable) P4 system.
With this SMP kernel, 2 of the 4 ports work, even with the USB
controller enabled. For the other ports, ifconfig gives the
error: "SIOCSIFFLAGS: Invalid argument ". Stracing ifconfig says:
socket(PF_INET, SOCK_DGRAM, IPPROTO_IP) = 4
...
ioctl(4, SIOCSIFADDR, 0xbfffc210) = 0
ioctl(4, SIOCGIFFLAGS, 0xbfffc140) = 0
ioctl(4, SIOCSIFFLAGS, 0xbfffc140) = -1 EINVAL (Invalid argument)
Stracing ifconfig for an interface that works shows similar lines,
but then the second SIOCSIFFLAGS ioctl succeeds.
Any suggestions?
Thanks,
