[Bug 1825058] [NEW] mac80211_hwsim unable to handle kernel NULL pointer dereference at0000000000000000
Public bug reported: The issue happens on 16.04 with linux-image-4.15.0-47-generic (as well as linux-image-4.15.0-45-generic). It also happens with linux- image-4.15.0-47-generic on 18.04 as well as the HWE kernel (4.18.0-17-generic). All test were done on 64 bit in a virtual machine and can be reproduced. It doesn't happen on 18.10 (mac80211_hwsim has other issues on this kernel that are solved in 19.04, most likely unrelated to this) or 19.04.

[Bug 1698042] Re: Nouveau driver blocks boot (17.04) on Optimus laptop with 960m
1. I assume the module nouveau is part of the kernel 2. I selected the kernel as close as possible to the current version; I don't know exactly which one it is since it doesn't boot. 3.

[Bug 1698042] [NEW] Nouveau driver blocks boot (17.04) on Optimus laptop with 960m
Public bug reported: Nouveau prevents booting on Optimus laptops (happened in recent kernels, on other distro, the issue wasn't present as of 4.4).

Trying to use nomodeset, it takes forever to "boot", I see errors during boot and when trying to load X.
