The branch main has been updated by wulf: URL: https://cgit.FreeBSD.org/src/commit/?id=2abdb305bd0c105226f6a71a8d3dc89698c9ef6b commit 2abdb305bd0c105226f6a71a8d3dc89698c9ef6b Author: Vladimir Kondratyev <wulf@FreeBSD.org> AuthorDate: 2025-04-28 21:39:28 +0000 Commit: Vladimir Kondratyev <wulf@FreeBSD.org> CommitDate: 2025-04-28 21:39:28 +0000 iichid(4): Do not send packets read in interrupt handler to hidbus if no hidbus and hidbus clients were attached and opened by users. iichid(4) enables interrupts before hidbus is attached and sending packets to it at this time leads to panic at boot time.
