kernel error (hardly reproducible)

I was doing too many things when this error occured, so I'm not able to report accurately. This happened just once for me on otherwise stable system.

Kubuntu Zesty
Linux peltan 4.10.0-14-generic #16-Ubuntu SMP Fri Mar 17 15:19:26 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
firefox/zesty-updates,zesty-security,now 52.0.1+build2-0ubuntu1 amd64

I remember to run ~10 applications; in Firefox, i clicked on a link to PDF, opening a PDF js viewer, then i closed the tab, then reopened the tab again and before the PDF loaded up back, i clicked on Back button. At that moment, Firefox freezed up. I switched to other applications, they worked normally, including HDD access. An exception: in terminal, `htop` was not able to load. I looked into dmesg output and found what is pasted below. After some time (1-2 minutes), all the applications started freezing up, probably when requesting hard disk I/O. No other option that hard-reboot the computer.

Please tell me what other gatherable information shall i append.
