Description Jan Boeschow 2004-06-19 04:19:27 UTC

Distribution: Gentoo 
Hardware Environment: Athlon XP 2500+, NForce2 
Software Environment: 
Problem Description: NForce Ethernet Adapter doesn't get an IP over DHCP on 
Kernel 2.6.7. Worked on 2.6.6 
 
Steps to reproduce: Compile NForce Ethernet into kernel.

Comment 1 Manfred Spraul 2004-06-19 12:08:35 UTC

Not an forcedeth bug: there were no code change between 2.6.6 and 2.6.7, only
sparse tags were added.
My bet: irq routing.
Please compare /proc/interrupts, dmesg, lspci -vxx between 2.6.6 and 2.6.7 - any
changes?
Do you use ACPI?

Comment 2 Jan Boeschow 2004-06-20 07:43:46 UTC

No diffs in lspci and /proc/interrupts. 
 
But it seems that there are problems while booting:

Disabling IRQ #11 
 
So USB, bttv and forcedeth are using irq11. None of them work in 2.6.7. 
 
And yes, I#m using ACPI. But also in 2.6.6 and there it works.

Comment 3 Daniel Eriksson 2004-06-29 05:50:57 UTC

Confirming. I have the exact same problem, and I'm also using forcedeth on a
nForce2 motherboard. Everything worked nice in 2.6.6, in 2.6.7 (or 2.6.7-rcx) it
does not. I also get the same errors about irq11 being disabled because nobody
caring. When trying to connect to Internet I just get the following:

NETDEV WATCHDOG: eth0: transmit timed out

When searching lkml I found the following: http://lkml.org/lkml/2004/5/30/129
which seems to be the same problem. The strange thing is that for Lee everything
works again after enabling acpi. I've always had acpi enabled. Now I've tried
disabling it, makes no difference.

(btw, I don't know if usb works in 2.6.7. Is it relevant to test it?)

Comment 4 Daniel Eriksson 2004-07-02 08:47:27 UTC

Searched a bit more. Guess this bug should be marked as a duplicate of #2846?

Comment 5 Jan Boeschow 2004-07-02 09:01:50 UTC

Oh yeah, seems so. 
 
I hope it will be fixed in the next vanilla release. 
 
Greets, Jan

Comment 6 Andreas Kuckartz 2005-04-23 05:25:04 UTC

Can this bug be closed?

(It is old and has nothing to do with the bug tracker)

Comment 7 Jan Boeschow 2005-04-23 07:02:28 UTC

Can be closed. 
 
Thanks.
