There seems to be an intermittent failure on the s390 host in
the qemu:block / io-qcow2-copy-before-write test:
https://gitlab.com/qemu-project/qemu/-/jobs/4737819873
The log says the test was expecting to do some reading
and writing but got an unexpected 'permission denied'
error on the read. Any idea why this might happen ?

Same failure, previous job:
https://gitlab.com/qemu-project/qemu/-/jobs/4736463062
This one's a "Failed to get write lock" in io-qcow2-161:
https://gitlab.com/qemu-project/qemu/-/jobs/4734846533
(I'm not sure whether there's something up with the s390
at the moment -- it seems to be producing these odd
failures, not always in the iotests. I'm wondering if
it's just running too slowly and we're hitting race
conditions in test cases.)
thanks

And I can only reproduce with Ubuntu (RHEL,SLES,Fedora are fine). Upstream kernel on Ubuntu does not help, so I assume it must be something in the libraries or config.
