Description of problem: Can't initiate two bridge adapters on boot. How reproducible: 100% Steps to Reproduce: I use diskless boot via iSCSI and multipath. Dracut takes params from grub2: iscsi_initiator=iqn.2001-01.local.domain:node1 netroot=iscsi:@10.0.0.2::3260::iqn.2001-01.local.domain:iscsitest.lv_node1 netroot=iscsi:@192.92.92.108::3260::iqn.2001-01.local.domain:iscsitest.lv_node1 ifname=enp2s0:10:fe:ed:03:aa:51 ifname=enp4s0:f4:6d:04:e6:78:80 ip=enp2s0:dhcp ip=enp4s0:dhcp Both adapters acquire their addresses, then make connection to iSCSI target by two distinct IP, mutlipath makes a dev. Now I'm trying to make bridges on this adapters, for VMs. Used dracut params: iscsi_initiator=iqn.2001-01.local.domain:node1 netroot=iscsi:@10.0.0.2::3260::iqn.2001-01.local.domain:iscsitest.lv_node1 netroot=iscsi:@192.92.92.108::3260::iqn.2001-01.local.domain:iscsitest.lv_node1 ifname=enp2s0:10:fe:ed:03:aa:51 ifname=enp4s0:f4:6d:04:e6:78:80 bridge=br0:enp2s0 bridge=br1:enp4s0 ip=br0:dhcp ip=br1:dhcp But only one bridge activates (enp2s0 at my case, first one in alphabetical order), then iSCSI connection crashes, because second adapter is inactive and cannot reach required network. Why can't I have two bridges on boot?
Can you boot with "rd.debug" on the kernel command line and attach /run/initramfs/rdsosreport.txt ?? Also why "Version: 7.3" ? Which version of dracut? Which version of RHEL?
Message about alphabetical order was incorrect, the only starting bridge is the last one in kernel params, in case of this: bridge=br1:enp2s0 ip=br1:dhcp bridge=br0:enp4s0 ip=br0:dhcp only br0 starts succesfully. Adding "bootdev=br1" doesn't fix it. There's no rdsosreport.txt after adding "rd.debug", but "messages" got additional info. According to logs, br1 (first one in kernel commandline) doesn't initiate at all. dracut Version: 033-161.el7_0.173 /etc/redhat-release CentOS Linux release 7.0.1406 (Core)

yes, sorry, dracut currently only supports one bridge and one bond interface.
I think I am facing the same problem as well. Re-adjusting the bugzilla parameters wherever required. - Pushpendra
