Message-ID: <20230706170537.95959-1-richard.henderson@linaro.org> (raw)
Thanks for the test case, Richard WMJ. Using the fedora rawhide
kernel-core-6.5.0-0.rc0.20230703gita901a3568fd2.8.fc39.x86_64.rpm
I was able to reproduce the problem within 30 iterations.
I'm now at 650 iterations and counting.
