Hi!
While doing stable-8.1.1 preparation, I've a CI failure of ubuntu-20.04-s390x-all here:
https://gitlab.com/qemu-project/qemu/-/jobs/5132720046
▶ ERROR:../tests/qtest/xlnx-canfd-test.c:265:match_rx_tx_data: \
assertion failed ((buf_rx[size] & DLC_FD_BIT_MASK) == (buf_tx[size] & DLC_FD_BIT_MASK)): (2281701376 == 2147483648)
qemu:qtest+qtest-aarch64 / qtest-aarch64/xlnx-canfd-test \
ERROR 0.77s killed by signal 6 SIGABRT
Re-run of this test went successfully. However, the assert looks
a bit scary, and the fact that it does not fail in a reliable way
is a bit troubling too. Is it a flaky test or there's something
else in qemu with concurrent threads?
I don't see this assert in previous test runs. But ubuntu-20.04-s390x-all
test fails quite often due to other reasons, so it isn't conclusive.
Should something be done with this?
The testing is done for commit f2fc49c302036315db6e8c9f74592decc3be0476,
which is in staging-8.1 branch only temporarily.
Thanks,
/mjt

I tried with staging-8.1 and didn't see this error. I ran it with registry.gitlab.com/legoater/qemu/qemu/fedora-i386-cross:latest on a x86 host machine. Can you please share more about how you are running
the testes? It will be greatly helpful to me in reproducing the issue and fixing
it.

I simply ran :
