Bug report

Bug description:

Since the Fedora builders were upgraded to Linux kernel 6.10.4 and/or 6.10.5, we see the following test failures when we build CPython on Fedora Linux 39, 40, 41, or 42:

I was able to reproduce this by upgrading a Fedora Linxu 39 ppc64le machine from an older kernel (6.8.x) to 6.10.6-100.fc39.ppc64le. The failures were not present with the older kernel but are present with the new one. No need to rebuild Python on the new kernel, just run it (e.g. via python3.12 -m test test_asyncio -wW -j8).

This is similar to #122136 but unlike that, this only happens on ppc64le. This also affects all the supported CPython versions we ship.

CPython versions tested on:

3.8, 3.9, 3.10, 3.11, 3.12, 3.13

Operating systems tested on:

Linux
