[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:

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 :(
