Subject: tg3/Broadcom gigabit driver just got worse in 2.4.23-pre3

Hi Jeff et all,

I just tried 2.4.23-pre3 with results that are disastrous, for me at least.

As you will remember, I'm the one who has to do an ifconfig down/up cycle
on my asus A7V8X mobo with built-in Broadcom chip. But after the updates
in -pre3 the chip no longer will work at all.

In fact, if I try 'ifconfig eth0 down' the command hangs forever and chews
up 99.9% of the CPU. No packets are ever transmitted in spite of a normal
'ifconfig' output after bootup. The chip is correctly identified in dmesg:

eth0: Tigon3 [partno(BCM95702A20) rev 1002 PHY(5703)] (PCI:33MHz:32-bit)
10/100/1000BaseT Ethernet 00:e0:18:d2:a6:c1

and lspci:
00:09.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5702 Gigabit Ethernet (rev 02)
Subsystem: Asustek Computer, Inc.: Unknown device 80a9
Flags: bus master, 66Mhz, medium devsel, latency 64, IRQ 10
Memory at f1800000 (64-bit, non-prefetchable) [size=64K]
Expansion ROM at f7ff0000 [disabled] [size=64K]
Capabilities: [40] PCI-X non-bridge device.
Capabilities: [48] Power Management version 2
Capabilities: [50] Vital Product Data
Capabilities: [58] Message Signalled Interrupts: 64bit+ Queue=0/3 Enable-

The data above were taken from 2.6.0-test4, but are the same in 2.4.23-pre3.

I would ask that you please not apple these recent changes to 2.6.0 until
we figure out what the problem is.

Again, I offer to do whatever testing/patching/whatever that I can do to
get this resolved, but you'll need to give me some specific instructions.

Thanks!

Same here but it's a 5705M in a laptop. Tried backing out just the
changes to the tg3 driver but couldn't get it to build correctly.

Cheers,
Scott

Does 2.4.23-pre2 work for you?

Yes, as long as I do the one-time ifconfig down/up cycle
after each reboot -- the same as it's been since 2.4.-21-pre5.

The really bad stuff was just introduced yesterday in 23-pre3.
