Subject: tg3:No interrupt was generated using MSI, switching to INTx mode. Please report this failure to the PCI maintainer and include system chipset information.

Hi @all,

we have installed a dual port Brodcam Gigabit Ethernet NIC, and get the
following error in dmesg:

tg3: eth1 No interrupt was generated using MSI, switching to INTx mode.
Please report this failure to the PCI maintainer and include system
chipset information.

Who is responsible for this error message? We are using Kernel 2.6.21.1
and the NIC Chipset is a Broadcom BCM5715CKPBG

Regards,

Marc

Many networking developers do not read linux-kernel

This message means that your system chipset (not the NIC) does not
support MSI. Please provide lspci -vvv to show the system chipset on
your system. Thanks.

Please post your full dmesg output from bootup, lspci -vvv output and
what kind of motherboard or system you're using.

Also it would be useful to test a newer kernel to see if the problem
still occurs. 2.6.21 is quite old these days.
