Hi,

All tested kernels had the same issue (2.6.22, 2.5.25.4 & 2.6.28.1).

dmesg |grep tg3:

tg3.c:v3.97 (December 10, 2008)
tg3 0000:01:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16
tg3 0000:01:00.0: setting latency timer to 64
tg3 0000:01:00.0: PME# disabled
tg3 0000:02:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17
tg3 0000:02:00.0: setting latency timer to 64
tg3 0000:02:00.0: PME# disabled
tg3 0000:01:00.0: PME# disabled
tg3: eth0: Link is up at 1000 Mbps, full duplex.
tg3: eth0: Flow control is off for TX and off for RX.

Now here it booted @ Gbit speeds!

Was there a version of the kernel where this device worked reliably?

Can you post the driver sign-on messages?  (I'm looking to see if ASF
is enabled.)

I surely tried other cables. But its surely not the cable because:
1) We tried other cables
2) After a reboot it works, or after a mii-tool -R
3) We have this issue on like +100 servers :(

The servers are connected on a Dell PowerConnect 6248 switch.

Sincerely

Hello!

Here is a mii-tool -vvv on a box that doesn't advertise gbit speeds! It 
just doesn't advertise gbit @ random, sometimes it does, sometimes not! 
Without any logic in it!

# mii-tool  -vvv
Using SIOCGMIIPHY=0x8947
eth0: link ok
    registers for MII PHY 1:
      1000 794d 0143 bed0 05e1 0000 0064 2001
      0000 0300 0000 0000 0000 0000 0000 3000

Register 1 shows that autoneg did not complete (bit 5 is not set).
The tg3 device has advertised 10/100/1000 in register 4 and register 9,
but registers 5 and 0xa (link partner's advertisement registers are 0).

When it works, these registers should look very different.

Have you tried other cables?  What is the link partner?
