``SIOCSIFFLAGS: Try again'' !?!

Post by Thai-Anthony La » Thu, 06 Mar 1997 04:00:00



Howdy...
        I was wondering if anyone could help me figure out why I am
getting/what is causing the following error message:
"SIOCSIFFLAGS: Try again".

This is returned when ifconfig tries to ``up'' the network interfaces, in
particular eth0 on one of my Linux machines.  The box has two 3Com 3C590
EtherLinks, each connected to a different network.  Here's a clipping
from /proc/pci:
--- start
  Bus  0, device  14, function  0:
    Ethernet controller: 3Com 3C590 10bT (rev 0).
      Medium devsel.  IRQ 10.  Master Capable.  Latency=248.  Min Gnt=3.Max
Lat=8.
      I/O at 0xff80.
  Bus  0, device  13, function  0:
    Ethernet controller: 3Com 3C590 10bT (rev 0).
      Medium devsel.  IRQ 5.  Master Capable.  Latency=248.  Min Gnt=3.Max
Lat=8.
      I/O at 0xff40.
--- end

Currently, the eth1 interfce works fine, but the eth0 returns the peculiar
message about SIOCSIFFLAGS.  I've switched the two cards and have received
the same result.  I've also tried running the 3Com DOS configuration utility
and found that both cards are working and fully operational.  Any idaes/insights/
information/expertise regarding the ``who, what, where, when, why, and how''
of this error message would be much appreciated.  Thanx.

thanx again.

There is a reference to this in the Ethernet-HOWTO.  Try this link.
(The item is in section 3.7.11)

I had the same problems with only one card  ( 3c509 ). After ciging the
command       route add <ipadresses to gateway and hosts and so...> things
started to work.

se man route for details.

The error "SIOCSIFFLAGS: Try again"  could be a result of a PCI bios
messing
up interrupts. On my Intel PPRO Venus board the PCIBIOS assigns the same
interrupt to several devices. Linux is able to share many interrupts,
but
not all. Such a conflict results in the above message (for 3c590/3c905
cards)

Chel is almost certainly correct... I had similar problems when
dealing with 3C59x cards in Dell machines.  The Dell version of the
AMI BIOS [ptui!] doesn't provide any way to override the
interrupt-sharing, or allow for manual assignment of PCI slot INTA
lines to individual IRQs.

In the current kernel series (I run 2.0.28 here), the 3C59x driver does use
PCI shared interrupts... so you should be able to have two or more
Vortex cards in a single machine, as long as you're not trying to use
another PCI device whose driver _cannot_ share interrupts.  This
wasn't true of the 1.2.13 and early 2.0 kernels.

Do you have an alias set for both eth0 and eth1 in /etc/conf.modules?  Or
are you just using something like insmod <driver>?
