(This is a mass-update to all current FC6 kernel bugs in NEW state) Hello, I'm reviewing this bug list as part of the kernel bug triage project, an attempt to isolate current bugs in the Fedora kernel. http://fedoraproject.org/wiki/KernelBugTriage I am CC'ing myself to this bug, however this version of Fedora is no longer maintained. Please attempt to reproduce this bug with a current version of Fedora (presently Fedora 8). If the bug no longer exists, please close the bug or I'll do so in a few days if there is no further information lodged. Thanks for using Fedora! Per the previous comment in this bug, I am closing it as INSUFFICIENT_DATA, since no information has been lodged for over 30 days. Please re-open this bug or file a new one if you can provide the requested data, and thanks for filing the original report! |
Description of problem: On our system, the ifenslave detach (ifenslave -d) as executed in ifup-eth and ifdown-eth to set up and take down bonding hangs the machine. Version-Release number of selected component (if applicable): How reproducible: We are using 8139too and pegasus modules as eth0 and eth1 respectively. We set up bonding using a static IP and the machine will lock when bringing down the interface. Using dhcp it will also invoke "ifenslave -d" when bringing up the interface and it will lock up there too. Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info: It's easily fixed by using sysfs to detach the slave devices. Maybe it's time to update initscripts to use sysfs instead of ifenslave when setting up or shutting down bonding devices?? I've updated ifup-eth where it starts bonding with dhcp and replaced "ifenslave -d $DEV $DEVICE" with: echo "-$DEVICE" > /sys/class/net/${DEV}/bonding/slaves Also updated ifdown-eth and the line "/sbin/ifenslave -d ${MASTER} ${DEVICE} 2>/dev/null" with: echo "-$DEVICE" > /sys/class/net/${MASTER}/bonding/slaves I'm not sure what ifenslave does different exactly, but using sysfs to detach no longer causes hangups on our system.
