3COM 3c905c again

From: Jonathan Lane <hidden>

Okay, I swapped cards around, and it turns out that *anything* in
PCI slots 3-6 are not correctly configured (this is on a UMAX S900).
I moved the USB card and NIC to slots 1 and 2, and my video card
to slot 4, which appears to be working (although I've not tried
using X yet, as XF86 4.0.1 is currently broken...).

However, now I am having another problem:  When I ping the machine,
I see the RX light on the NIC flash, but the source machine doesn't
get any responses.

A few things to note:  Every once in a while, I see the following
message:

	eth1: Setting promiscuous mode.

Also, in my syslog, dhcpd complains with:

Aug 27 16:42:20 colour dhcpd-2.2.x: DHCPDISCOVER from 08:00:46:05:9c:c8 via eth1
Aug 27 16:42:20 colour dhcpd-2.2.x: no free leases on subnet 192.168.1.0

(Ignore the date, my clock had yet to be set).  But this indicates that
packets *are* getting thru, as the MAC address shown above is correct.

If anyone can shed some light on this matter, I'd greatly appreciate it.
I'd also like to know why the last four PCI slots don't work properly,
although it appears it's not incredibly important now, unless X doesn't
work...

TIA,
Jonathan

X4 works for me[tm] on my 9600 with debian. Of course, I seem to be the
only person on the planet who's got X working in a 9600, with an imstt, in
the bottom slots, without offb, etc etc etc, so ymmv.

Probably from dhcpcd sending out a broadcast to find a DHCP server.

Also, in my syslog, dhcpd complains with:

Aug 27 16:42:20 colour dhcpd-2.2.x: DHCPDISCOVER from 08:00:46:05:9c:c8

Check your DHCP server configuration and logfiles. It would appear your
server doesn't want to give your client an IP address.

Note that when dhcpcd doesn't get an IP address, it will deconfigure the
interface it's on, thus not allowing any traffic through.

If anyone can shed some light on this matter, I'd greatly appreciate it.

I think there's some PCI bogosity in the standard 2.2 kernels when it comes
to PCI-PCI bridges. I've had fairly good luck with 2.2 with a PCI patchset
that I don't recall the URL of, and more recently, with 2.4 rsynced from
penguinppc.

Someone else can answer with more authority on the subject.

As for the PCI slots, I'm afraid I can't be much of any help.  The error
you are describing in your syslog, that basically means that your DHCP
server does not have any more IP addresses to give out to clients.  If you
administer this server, then you might want to consider adding more
addresses to the scope.  When the machine comes up, I'll bet if you do an
ifconfig, and take a look at your eth1 adapter settings (if it's there), it
won't have an IP address, which explains why packets aren't bouncing back
to your ping source.

This might work better with current bitkeeper _2_3 kernels (currently
at 2.4test12-pre-something). There's some new PCI code there that should
handle multiple PCI busses more gracefully.
