Hi Christian,
I appreciate your help. Those were good suggestions.

558s dmesg: read kernel buffer failed: Operation not permitted
This isn't from the test, this is our test runner that tries to capture
dmesg before and after [3] each test, for debugging purposes. These get
exported as artifacts, and made available in our CI. This fails with
rootless podman because reading dmesg is a privileged operation by
default.
Thanks for the correction.
On the host, could you try
$ sudo sysctl kernel.dmesg_restrict=0
and then run the test again. This should enable dmesg capturing by
regular users, and if it really is the OOM killer, it should be logged
there.
Possibly another factor: the kernel overcommits memory by default. If
more actual memory is used than physically available, the OOM killer
will kill something, which would neatly fit to the "Killed" above.
You can turn off overcommitment with:
$ sudo sysctl vm.overcommit_memory=2
Perhaps that also changes something.

Could you share the output of rocminfo with both 6.1 and 6.10?
I don't think it needs to be run in the test container, at least I don't
see why the result on bare metal should differ.
See attached for rocminfo logs from Debian Stable. Here's the diff:

I also just noticed that [2] is segfaulting, so there's clearly another
issue even with the older kernel. I hadn't noticed that before. It
didn't do that when rocfft 6.1.2 was first uploaded [4].
