Title:
Random total system freezes (resolved)
Status in linux package in Ubuntu:
Expired
Bug description:
I have an Intel 7260 WiFi card in my desktop (lspci output: 09:00.0
Network controller: Intel Corporation Wireless 7260 (rev bb)), running
18.04. All the way since 17.04 I have experienced random freezes,
where the entire system would be unresponsive, I was unable to
Ctrl+Alt+F1 to a different console, and I couldn't connect to it via
ssh. After upgrading to 17.10 (and a fresh install of 17.10), and
subsequently upgrading to 18.04, the issue intensified, appearing at
least hourly, often quicker than that, and only a hard reset would let
me access my system again. The issue is also present in Linux Mint
18.3. Freezes could happen at any time, regardless of usage (or just
idling).
After getting a tip that this might be caused by the WiFi card, I
looked at the provided firmware from Intel's site, and compared the
files to the files present in /lib/firmware/. The file provided by
Intel for my specific card is iwlwifi-7260-14.ucode, but the files
present in the folder were the numbers 7, 8, 9, 10, 12, 13, 16, and
17. Downloading the firmware from Intel, and adding the -14 file to
the folder solved the issue of the screen freezing, and the issue has
not appeared for the ten hours I've been running since applying the
fix.
