Hi,
thanks for your quick reply.
On receiving your email 23 hours ago, I set that option in modprobe
and rebooted my laptop. It works fine till just now when that bug
occurs again when I was just viewing some man-page. Then I have to
reboot my laptop to bring network back alive, in order to reply you
this email :-)
I've attached the lasted systemd journal, it seems a little different
from yesterday's dmesg log... Could you take a look at it? And I found
that every time I boot up my laptop there is a little line of message
like:
Nov 04 17:07:36 xenien kernel: iwlwifi 0000:03:00.0: can't disable
ASPM; OS doesn't have ASPM control
Does it have something to do with the bug?
Though this bug only occurs at a frequency of ~1 per day but it's
somewhat unexpected and annoying... ;-(
Sincere regards.

Hi, Sedat.
I am so sorry that I was in a hurry to reply in Gmail web interface
so I forgot to set "Text-only" mode and violated the mailing lists
etiquette.
I'll keep them in mind.

Hi,
Here two hints for "correct asking" on Linux-related mailing-lists:
Documentation/email-clients.txt [1] says:
"The default setting of not composing in HTML is appropriate; do not
enable it."
Documentation/development-process/2.Process [2] says:
"- Avoid top-posting (the practice of putting your answer above the quoted
text you are responding to). It makes your response harder to read and
makes a poor impression."
Checkout Documentation/ directory for more help/hints.
