Description Calvin Austin 2003-09-03 21:39:20 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; SunOS sun4u; en-US; rv:1.1) Gecko/20020827

Description of problem:
In SMP mode the broadcom network cards initialize ok according to dmesg,  but
fail to bring a network up. The same cards work in UP mode. The tg3 module is
successfully loaded

The driver is tg3.o , the source is v1.6, SMP binary is 64240bytes, 
the UP 64384

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.boot SMP kernel
2.ifconfig -a
3.ping machine

Actual Results:  cannot assign ip address through dhcp

Expected Results:  should bring up a card with ifup eth0

Additional info:

Broadcom NetXtreme BCM5704 Gigabit
beta 1 worked
Have needed to add acpi=off to even get SMP beta 2 to boot
Comment 1 Arjan van de Ven 2003-09-04 03:13:11 EDT
this sounds like an irq routing problem; without ACPI you don't get irq's routed
to the tg3 card
Comment 2 Jim Paradis 2003-09-04 11:11:27 EDT
Can you tell me what model system you are using, and describe how the SMP boot
fails (if you can produce and attach a serial console dump that would be ideal!)

serial console output with SMP without acpi=off
Comment 4 Jim Paradis 2003-09-10 13:04:19 EDT
Could you try again?  The crucial part of that serial capture (crash location
and beginning of register dump) is garbled.
Comment 5 Matt Wilson 2003-09-25 20:53:32 EDT
any more info on reproducing this?
Comment 6 Calvin Austin 2003-09-26 01:43:20 EDT
In email with Jim I believe I am seeing an SMP bug in the serial console too. 
I have manually typed in the last lines of the console output, the output is
being overwritten by other output lines. I'll see if I can decipher the rest

Code:  Bad RIP value.

Please run the /usr/sbin/dmidecode and attach the output.  Thanks!

Comment 9 Calvin Austin 2003-09-26 19:30:54 EDT
On deciphering the crash myself I noticed we never get out of acpi
initialization as such, so the tg3 driver could be a red herring in this case.

Comment 10 Jim Paradis 2003-12-02 14:26:51 EST
Conversations with customer and AMD show that this is happening on a
prototype platform that will not go into production and that we do not
have access to.  We can only support such configurations on a "best
effort" basis.  Since we couldn't resolve the problem I'm changing
this to WONTFIX.
Comment 11 Calvin Austin 2003-12-12 19:20:05 EST
Good News I've been meaning to post. With a BIOS update and AS 3.0
Final release (this was originally reported on beta) the network card
now works in SMP mode
