This is my first time reporting one for a linux distro, and I'm more or less doing so based on information I was told while investigating a separate issue related to my audio devices. On boot, along with the error I was looking for, I noticed a number of UBSan errors pop up. I asked about them in a linux-related discord server and their first question was whether the kernel was compiled with Clang. Now, because I never mess with the kernel, I told them I wasn't sure. That was when they told me that it's a kernel bug that invoked undefined behavior and left my kernel in an erroneous state. Here are the errors in question: [ 5.036942] UBSAN: array-index-out-of-bounds in /build/linux-SXblTa/linux-6.5.0/drivers/gpu/drm/amd/amdgpu/../pm/powerplay/hwmgr/smu7_hwmgr.c:3669:4 [ 5.036951] index 2 is out of range for type 'ATOM_Tonga_MCLK_Dependency_Record [1]' [ 5.041843] UBSAN: array-index-out-of-bounds in /build/linux-SXblTa/linux-6.5.0/drivers/gpu/drm/amd/amdgpu/../pm/powerplay/hwmgr/smu7_hwmgr.c:3676:4 [ 5.041852] index 7 is out of range for type 'ATOM_Polaris_SCLK_Dependency_Record [1]' Because I'm not 100% sure what all goes into a bug report like this, I will be providing the output of lsb_release -rd, hyfetch, and creating a list of my system's specs in hopes that it will help provide some sort of clarity. lsb_release -rd Output: ----------------------- No LSB modules are available.

I'm not sure though. I also went ahead and included an attachment of the photo I took of the error itself, maybe it'll help in some way. I'm also unsure if there's a package related to this bug, or what that package would be. Sorry. As for the last two things stated in the guidelines for reporting a bug, what I expected to happen was to see the error about my USB device along with some of the general jargon that pops up on boot that I typically don't have to worry about. Instead what happened is that based on what someone else told me, I found a bug in my kernel, although I'm not knowledgeable enough to know if it's a serious bug, or something that's really not that big of a deal. I'll leave that one up to you guys To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2045992/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
