[Kernel-packages] [Bug 2039409] Re: System freezes with UBSAN: array-index-out-of-bounds in iwlwifi code
A few days after reporting, I noticed that VLC media player was terminating its process whenever I would seek ahead in a video. I found a workaround by disabling hardware video acceleration (VA API). I had been watching a lot of videos in Chrome when the system freezes in this bug were happening. I tried disabling hardware video acceleration in Chrome, and haven't had any system freezes since (4 days or so). I believe therefore that this bug is related to the Intel hardware video acceleration system somehow. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-signed-hwe-6.2 in Ubuntu. https://bugs.launchpad.net/bugs/2039409 Title: System freezes with UBSAN: array-index-out-of-bounds in iwlwifi code Status in linux-signed-hwe-6.2 package in Ubuntu: Confirmed Bug description: System consistently freezes requiring hard reset every few hours.

After over a week crash-free after disabling hardware video decoding, I started getting the same crashes again today, despite not using any hardware video decoding anywhere that I can tell.
