Thanks for your reply. I have a GTX 1080 and 495.44 drivers. The crash happens just after the same warning as you. I'm running the 5.15 rc6 kernel without issue. The boot problems started since 5.15 rc7 upgrade , and the only differences between this versions are : - Enable CONFIG_FAIL_SUNRPC for debug builds (Justin M. Forbes) - fedora: Disable fbdev drivers and use simpledrm instead (Javier Martinez Canillas). So i will try to build the kernel without the second patch and make a try. Thanks again. _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
