Hi, I just installed CentOS 4.4 x86_64 on our new 2 x Dual Core Opteron Server. First the system was unstable, but I after turning of Power-now it runs stable (anyone else experienced this?). However the following line in dmesg puzzles me: tg3: eth0: No interrupt was generated using MSI, switching to INTx mode. Please report this failure to the PCI maintainer and include system chipset information. Has someone else experienced this? What does it mean and who am I supposed to contact? Sorry if this is a stupid question, but a simple pointer would be appreciated. Apart from this message the system runs fine. Hardware Information: Server: Supermicro 816S-R700 Motherboard: Supermicro H8DSP-8 Chipset: ServerWorks HT2000 / HT1000 Processors: 2 x Opteron Dualcore 2.2 GHz RAM: 4 GB Ethernet is of course on the mainboard. I have already upgraded the tg3 driver with the latest version from Broadcom, but the line in dmesg still appears. regards, Andreas Micklei
