Debugging Linux Kernel Crash

Error description:

Almost everytime I'm uploading a bigger file (65MB in this case) via. my browser (Firefox, build provided by mozilla.org as .tar.gz), my system crashes. Issue especially happens when I'm doing different things at the same time. (Watching a video, reading email + uploading a file). System is using an SSD, bug also appears if the file is served from /tmp, though.
