Still no go with 10mb on 100mb card

Still no go with 10mb on 100mb card

[Stephan van Hienen]

just downloaded the newest rpms etc.
and reinstalled the ultralinux 

but the same as with my own compiled kernel:

no go with the sun happy meal on eth0 (on the scsi/ethernet pci board)
it's connected to a cable modem at 10mbit/sec half duplex
and it gives ethernet time outs

eth1 (the onboard sun happy meal) works ok at 100mbit full duplex

whats up ? 

( i'm still stuck at kernel 2.1.109)
cause after that console display disapeared 
and  when i then tried to compile the newest one (after my vacation)
i had no go with the ethernet :((

All I can say at this point is that you  must have some very strange
ethernet switch/hub because every single switch/hub I test on here at
Cobalt with both 10 and 100baseT & both full and half duplex all work
correctly with the happy meal.

Try another hub/switch/network if you can, I bet it works.

Then we can figure out what is so strange about the one where you have
the problems.

the card is directly connected to a LANcity cable modem

the only thing i can think of is that the ethernet adres is changed when i
boot the 2.1.125 kernel

i will look this thing out this week
maybe (i hope) it's this

this because the cablemodem only responds to the ethernet adress that has
been programmed in the eeprom (or something) inside the cablemodem

it's only strange that 2.1.112 works ok

and that 2.1.125 doesn't :(

I didn't see the beginning of this thread but the message above
caught my eye. When I tried to install on my ultra5 here (for
details see my "Mixed news: new IP 1.0.9 on Ultra5" message) I had
what sound like a very similar problem with the hme on the SunSwift
(scsi/ethernet) board. It was detected as eth0 successfully (the
onboard hme was detected as eth1) but it didn't seem to be able to
receive packets properly. tcpdump from the remote side showed it
sending out arp queries and showed the corect reply being sent back
but the ultra just kept sending out arp queries as if it hadn't
received anything. The card itself works fine with Solaris. I ended
up removing the card completely after which an installation went
fine with the on-board hme (apart from later non-network problems
that I mention in the other message).

There were some problems with scsi/eth PCI cards on Ultra5's earlier,
when was the most recent kernel you have tried with the card in the
machine?  We believe this particular to be fixed by now.

This was with Jakub's UP 1.0.9 update last Friday (30 Oct). For more
details, see my "Mixed news" message. I'm about to follow that up
right now with details of my attempt today with Jakub's latest
update that he put there on Monday.
