RPi Kernel memory leak leads to OOM killer running on idle system.

[Barry Scott]

A number of us are seeing a reproducible kernel memory leak on RPi.

There is a bug https://bugzilla.redhat.com/show_bug.cgi?id=2279327
and a thread in discuss about it with additional
details:
https://discussion.fedoraproject.org/t/high-memory-usage-in-f40-on-rpi-4-...

Kernel 6.5.6 does not have a leak, but current kernels do.

Anyone know if this is being looked at?

Barry

Can you specify what you mean by "current kernels", I believe there is a
aarch64 memory leak fix in 6.8.9, which is currently in testing. There's
more info in the following bug:

Sorry should have provided a version 6.8.8 is what I have.
I'll install the 6.8.9 kernel and test.
