Hi Ramesh,
There are numerous reports (mostly old, afaics) of the issue you describe, but
with various suggested reasons.
I suspect the avahi related part is a consequence rather than a cause - I didn't think
avahi was capable of disabling interfaces, the message looks like it's updating a
table/list (etc) and "...no longer relevant..." messages appear in my syslog if
I deliberately disconnect from wifi.
Please can you provide syslog extracts from just before and during a time when
this has happened, using:
$ sudo cat /var/log/syslog | grep -i -E "avahi|network"
(must be capital -E and no spaces around the | inside the speech marks)
Is there anything that seems relevant in
$ sudo dmesg -T
?
Out of interest, did you try running for a while with just the power management
tweak?
Thanks,
Gareth
Yes, I believe I did. I did not use /sys/... power/control method.
Instead, I kept the network alive by "ping -i 60 <ext-gateway>".
However, I am not 100% sure of this. So, I will revert some of my
changes and get you the relevant logs.
Thanks for your continued interested in this matter.
Regards
Ramesh
