The configuration use for the building is the one available from Debian, see [2] and [3]. Unfortunately I don't have much information, when the issue arises the job seems to hang and it is cancelled by Gitlab due to a job timeout. So far I did some bisect to get the commit which introduces the issue and a quick check with latest Linux stable branch master to confirm the issue is still present. I know this is not a proper bug report but I thought it will be better to at least raise a comment. Thanks in advance, Walter [1] http://lists.infradead.org/pipermail/linux-um/2021-August/001657.html [2] https://packages.debian.org/bookworm/user-mode-linux [3] https://salsa.debian.org/uml-team/user-mode-linux -- Walter Lozano Collabora Ltd. _______________________________________________ linux-um mailing list linux-um@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-um
