The branch stable/13 has been updated by andrew: URL: https://cgit.FreeBSD.org/src/commit/?id=6136013a16f55ec21ae32e068bb425eb97fca250 commit 6136013a16f55ec21ae32e068bb425eb97fca250 Author: Andrew Turner <andrew@FreeBSD.org> AuthorDate: 2023-01-28 17:36:24 +0000 Commit: Andrew Turner <andrew@FreeBSD.org> CommitDate: 2023-05-15 07:59:43 +0000 Disable the arm physical timer when an irq exists Some firmware leaves the timers enabled. Ensure they are disabled if there are any physical timer interrupt resources to ensure we don't receive any unexpected interrupts from them.
