            Bug ID: 216920
           Summary: Running IDE eventually leads to BUG: kernel NULL
                    pointer dereference
           Product: Drivers
           Version: 2.5
    Kernel Version: 6.1.4-arch1-1
          Hardware: Intel
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri@kernel-bugs.osdl.org
          Reporter: gabriel@sullice.com
        Regression: No

Hello,

I do my best to provide details, but I am very much a novice so please bear
with me. I will not ghost this issue and I will be as helpful as I can be, but
I will have difficulty patching my kernel, for example.

My desktop has been freezing after its free memory nearly reaches zero. I can
consistently reproduce this behavior within a few minutes of opening my IDE
(any of the JetBrains products).

I have noticed that if I leave my system on for many days, it will eventually
report very little free memory and freeze. Unfortunately, I have not recovered
for logs after these events. However, within minutes of opening my IDE my
memory usage begins to increase rapidly. When I have nearly no free memory
left, my desktop freezes. By running "journalctl -b -1" after these events, I
am able to recover the error and stack trace included below.


I searched for similar but reports and
https://bugzilla.kernel.org/show_bug.cgi?id=216730 sounds similar, especially
regarding the Linux 5 -> 6 upgrade. I believe the situation started (or became
noticeably worse) after I upgraded in early December.

Please let me know if I can provide any additional details.

- Gabe
