Public bug reported: After using my computer (Dell Inspiron 3576, running Ununtu 16.04.6 LTS) for a while the wi-fi suddenly stops working. The rest of my apps and programs continue to run smoothly. However, when I open "System Settings" and then try to open "Network", the computer hangs and in order to get it working again I have to reboot it. The reboot takes forever; meanwhle, I get a black screen with this message: [75873.475364] BUG: unable to handle kernel paging request at ffffc90000d6e808 [............] IP [<ffffffffc0a80f1 fffffc0a80f12>] iwl_trans_pcie_read32+0x12/0x20 [iwlwifi] PGD 2569aa067 PUD 2569ab067 PMD 255a96067 PTE 0 Oops: 0000 [#1] SMP
