pci=bfsort doesn't help.it seems this option will ask kernel to use breadth-first when probing devices. However, lspci always shows the same result whatever the eth[N] order is.So I guess this has something to do with udev. This box uses an EL5,in which the udev version is 095. I think in the udev.c file udev will use the following sequence to name all the devices: udevd_main loops found device fork() call modprobe to load drivers I think this means udev cannot promise module loading order. could you give me more hint on this? 2008/1/3, Caetano, Greg <Greg.Caetano@xxxxxx>: > > Try "pci=bfsort" on the boot commandline and see if you get the consistency you are looking for. > > Greg Caetano > greg.caetano@xxxxxx > Red Hat Certified Engineer > RHCE#805007310328754 > > -----Original Message----- > From: redhat-list-bounces@xxxxxxxxxx [mailto:redhat-list-bounces@xxxxxxxxxx] On Behalf Of leilei175@xxxxxxxxx > Sent: Wednesday, January 02, 2008 8:25 PM > To: redhat-list@xxxxxxxxxx > Subject: how is udev integrated in redhat enterprise linux5? > > Hi, > > I have some question about the network device naming mechanism in enterprise Linux5. > On my box with 2 on-board network interface and another 2 intel network interface,the order of these four interfaces will change from time to time.I mean sometimes the 2 on-board are eth0 eth1,sometimes they are eth1 eth2. > > I know I can use MAC address to fix the order.I'm just curious about how could the order change boot by boot without any modification on configuration or hardware. > > could any one give some suggestion? > > Thanks > > -- > redhat-list mailing list > unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe > https://www.redhat.com/mailman/listinfo/redhat-list > > -- > redhat-list mailing list > unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe > https://www.redhat.com/mailman/listinfo/redhat-list > -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
