[Xen-users] AGAIN: unregister_netdevice: waiting for vif3.0 to become free. Usage count = 15
Hello everyone I''m back again with my problem: domUs become Zombies after shutdown with message "unregister_netdevice: waiting for vif3.0 to become free. Usage count =". I can''t reboot dom0, can''t restart affected domU because interface is locked and reboot process hangs forever. The problem is still here altrough I use the latest xen 3.0.2-2 with kernel 2.6.16.13. My server is P-IV with HT enabled. After long time of googling I''ve found a very interesting message related to this problem: http://permalink.gmane.org/gmane.comp.emulators.xen.devel/13607 Altrough it is related to kernel 2.6.12, my current kernel (net/bridge/br_if.c) seem to still contain this bug. At least in line 461 (br_del_if() function): if (!p || p->br != br) return -EINVAL; and Ryan Harper suggests to replace it with: if (!p || p->br != br || p->state == BR_STATE_DISABLED) return -EINVAL; and remove "brctl delif" calls from xen''s scripts. More read about this discussion: http://comments.gmane.org/gmane.comp.emulators.xen.devel/13554 Could anyone provide me any info how to get rid of this damn problem ? At the moment every shutdown/reboot of any domU for me ends with sysrq reboot of the dom0 server :( -- Best regards Anton Khalikov _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
