@You-Sheng, I honestly have been VERY out of the loop on linux kernel/hardware since the 2.4-2.6 days. I've been stuck in AWS for years ;)
Can you verify I'm understanding the situation correctly? It appears that the kernel in Eoan contains a driver that contains this issue, and the backport-iwlwifi package will receive the fix first in the form of a "much more recent driver from intel" made possible by DKMS? Is this interpretation correct? I'll go ahead and try this PPA and verify if it fixes the issue! Thinking about it a bit, does this mean that the firmware eaon ships is incompatible with the upstream kernel's driver, or that the upstream kernel driver just has a bug? Are the firmware / kernels tied together, and how do we get the right firmware that will work with the backport- iwlwifi packages? Thanks in advance for the clarification. Trying to come up to speed again. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1855637 Title: Intel AC 9260 (iwlwifi) completely unstable and halts cores in 19.10 Status in linux package in Ubuntu: Confirmed Bug description: After updating from 18.04 to 19.10, the entire system will freeze and eventually recover with many dmesg errors with backtraces and all sorts of errors around the iwlwifi module. I eventually restored to an 18.04 backup, but not before logging a lot of information and also validating that it reproduces with the 19.10 "Try Ubuntu" from the iso, so it certainly isn't an artifact of the upgrade (although ubuntu-drivers does appear a bit confused about iwlwifi when I did an upgrade, but that appears to be unrelated). It is worth noting that I also use the bluetooth module in this card, but it is connected via a cable to an internal USB 2 header to the system board and I believe it uses another driver entirely. I have additional external drives I can install test bed systems on to test fixes if need be, but it is worth noting that this is rock solid on 18.04.3 and the issue will reproduce within 15 minutes of watching youtube videos on 19.10. DMESG output from start of issues is attached.
