Bug Description
Probably during linking (or building) of chromium the system froze. REISUB worked and the system rebooted.
Looking in the syslog file the following line probably caused the freeze.
`BUG: kernel NULL pointer dereference, address: 0000000000000018` more in the attachment.
If you need anything more, let me know.
