Is this something new or been happening for a while? Does it happen
consistently? I just build the master branch and ran the tests on a very
old machine, I mean 13 years old. The host runs Fedora 40 with
libtpms-0.96-6 + swtpm-0.9.0 from the distro:
104/473 qemu:qtest+qtest-aarch64 /
qtest-aarch64/tpm-tis-device-swtpm-test OK 2.32s
2 subtests passed
I see some other non-TPM tests timing out but not this one. Same result
for TIS test on 2nd run.
104/473 qemu:qtest+qtest-aarch64 /
qtest-aarch64/tpm-tis-device-swtpm-test OK 2.51s
2 subtests passed
3rd run:
104/473 qemu:qtest+qtest-aarch64 /
qtest-aarch64/tpm-tis-device-swtpm-test OK 2.37s
2 subtests passed
4th run:
104/473 qemu:qtest+qtest-aarch64 /
qtest-aarch64/tpm-tis-device-swtpm-test OK 2.63s
2 subtests passed
If I run it as a single test on the command line like this then it
consistently works here - I ran it >10 times now.
