apport-collect is not useful, someone needs to read the initial comment and
backport
the existing fixes from 5.15.y

Bug description:
There's a regression with io_uring reported against 5.11-5.14 kernels,
see:

From reading the thread and looking at the history in
linux-stable/linux-5.15.y,
I assume that Linux 5.15.3 is the first fully fixed version.
And 5.10 was not affected.
Sadly all other versions are EOL for kernel.org.
But ubuntu provides 5.11, 5.13 and 5.14 based kernels,
which most likely have the bug.
I'm reporting it against linux-hwe-5.13 as that's what I test on most systems,
but others e.g. linux-oem-5.13 and linux-oem-5.14 have the same problem.
