Seems to me it is related to the filesystem. Can anyone elaborate on what is happening please ?

Thanks,

Re: Error messages regarding tasks hanging up

Is this happening after resuming from suspend or hibernation? It happened to me twice with 3.15.5 (now on 3.15.8, haven't experienced it since). Have you tried updating to the latest kernel through pacman?

Re: Error messages regarding tasks hanging up

Yes, it does happen after suspension or hibernation. I have not updated yet because I have not got time. However, I have seen this coming up time to time. If it is kernel issue, did you find any bug report in linux ?

Re: Error messages regarding tasks hanging up

I didn't really investigate the issue. I am unaware of any reports. My suggestion is to update at your earliest convenience.
