[SOLVED] Small periodic system freezes after resume from suspend

Hi everyone!
I am new to arch and a question get me stucked for a long time. It is that almost everytime I suspend the system to the ram, it is very fast and ok since the new kernel, but when I resume from suspend and then sometimes when I save files or other operations needing to sync to hdd, the hdd I/O reches 99%(I get this by the iotop command) and block the ui for muti-seconds,especially when I use eclipse and save an edited file. I googled for this question but there's no solution. I only find a post in this forum about this question here:https://bbs.archlinux.org/viewtopic.php?id=139087 but it doesn't give a clear answer. And I also read the wiki about the Small periodic system freezes and this wiki doesn't work because the issue appears only after resume from suspending. I have no idea So I open a new topic for the question.
Thanks in advance!
The related etc files:
this is the newest kernel, but the problem last for about half an year:

Re: [SOLVED] Small periodic system freezes after resume from suspend

from hdparm:

 AdvancedPM=yes: unknown setting WriteCache=enabled

Maybe the disk goes to sleep too often; this is bad even for your hdd life.

Do you set hdparm at boot or maybe a Power managment script does that?
Remember that hdparm settings are lost on hibernation/suspend, so you need to rerun it when the pc wakes up.

Anyway,at wakeup,  try to run

sudo hdparm -B 255 /dev/sda

To disable power managment.

It works like a charm! Thanks for your reply. This question really drove me crazy for long time. It really caused by wrong setting of APM.From your reply then I follow the instruction of hdparm wiki and make it automated.

Re: [SOLVED] Small periodic system freezes after resume from suspend

Glad you solved the issue.
Anyway,  if you are still interested in HDD power managment, try to experiment with lower hdparm values.
If it doesn't work (sometimes drives have a sort of hardcoded values that cannot be tweaked), you can still disable PM all togheter and resort to a userland tool.
Personally, i use hd-idle from AUR.
