Actually, I wasn't trying to reproduce it, I just started seeing it a few w= eeks ago, in CURRENT. I can reproduce it consistently, by using QEMU to run a PowerPC64 VM with a single core/thread (-smp 1). It happens only when there is no media in the emulated CD-ROM, a device that QEMU adds by default, unless -nodefaults is specified in command line. I've debugged it and this is what I've found: 1- After the CD probe is successful, GEOM will try to open the device, which will end up calling cdcheckmedia(), that sets CD state to CD_STATE_MEDIA_PREVENT. 2- Next, scsi_prevent() is executed and succeeds, the CD_FLAG_DISC_LOCKED f= lag is set and CD state moves to CD_STATE_MEDIA_SIZE. 3- Next, scsi_read_capacity() is executed and fails, state is set to CD_STATE_MEDIA_ALLOW, cdmediaprobedone() is called and wakes up cdcheckmedi= a(). 4- Then, when cdstart() is invoked to process CD_STATE_MEDIA_ALLOW, it first checks if CD_FLAG_DISC_LOCKED is set, and if so skips directly to CD_STATE_MEDIA_SIZE state. This will repeat the steps of bullet 3, entering= an infinite MEDIA_SIZE command loop. When there is a least another core/thread, the GEOM thread that performed t= he initial cdopen() will get scheduled again, closing the CD device, that will call cdprevent(PR_ALLOW) that clears the CD_FLAG_DISC_LOCKED flag and breaks the loop. So, apparently, the problem is CD_STATE_MEDIA_ALLOW being skipped when CD_FLAG_DISC_LOCKED is set. If I understand correctly, in this case, the st= ate should be advanced to CD_STATE_MEDIA size only when the current state is CD_STATE_MEDIA_PREVENT. --=20 You are receiving this mail because: You are on the CC list for the bug.= From owner-freebsd-scsi@freebsd.org Thu Nov 28 14:37:37 2019 Return-Path: Delivered-To: freebsd-scsi@mailman.nyi.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mailman.nyi.freebsd.org (Postfix) with ESMTP id 036801ABAAA for ; Thu, 28 Nov 2019 14:37:37 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from mailman.nyi.freebsd.org (mailman.nyi.freebsd.org [IPv6:2610:1c1:1:606c::50:13]) by mx1.freebsd.org (Postfix) with ESMTP id 47P0bh6MBbz4dpm for ; Thu, 28 Nov 2019 14:37:36 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: by mailman.nyi.freebsd.org (Postfix) id DA3581ABAA9; Thu, 28 Nov 2019 14:37:36 +0000 (UTC) Delivered-To: scsi@mailman.nyi.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mailman.nyi.freebsd.org (Postfix) with ESMTP id D9FBB1ABAA8 for ; Thu, 28 Nov 2019 14:37:36 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from mxrelay.nyi.freebsd.org (mxrelay.nyi.freebsd.org [IPv6:2610:1c1:1:606c::19:3]) (using TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits) server-signature RSA-PSS (4096 bits) client-signature RSA-PSS (4096 bits) client-digest SHA256) (Client CN "mxrelay.nyi.freebsd.org", Issuer "Let's Encrypt Authority X3" (verified OK)) by mx1.freebsd.org (Postfix) with ESMTPS id 47P0bh5VgVz4dpl for ; Thu, 28 Nov 2019 14:37:36 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from kenobi.freebsd.org (kenobi.freebsd.org [IPv6:2610:1c1:1:606c::50:1d]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (Client did not present a certificate) by mxrelay.nyi.freebsd.org (Postfix) with ESMTPS id A065527276 for ; Thu, 28 Nov 2019 14:37:36 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from kenobi.freebsd.org ([127.0.1.5]) by kenobi.freebsd.org (8.15.2/8.15.2) with ESMTP id xASEbap6057378 for ; Thu, 28 Nov 2019 14:37:36 GMT (envelope-from bugzilla-noreply@freebsd.org) Received: (from www@localhost) by kenobi.freebsd.org (8.15.2/8.15.2/Submit) id xASEbaAH057377 for scsi@FreeBSD.org; Thu, 28 Nov 2019 14:37:36 GMT (envelope-from bugzilla-noreply@freebsd.org) X-Authentication-Warning: kenobi.freebsd.org: www set sender to bugzilla-noreply@freebsd.org using -f From: bugzilla-noreply@freebsd.org To: scsi@FreeBSD.org Subject: [Bug 219857] panic in scsi_cd code Date: Thu, 28 Nov 2019 14:37:35 +0000 X-Bugzilla-Reason: CC X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: Base System X-Bugzilla-Component: kern X-Bugzilla-Version: CURRENT X-Bugzilla-Keywords: X-Bugzilla-Severity: Affects Only Me X-Bugzilla-Who: leandro.lupori@gmail.com X-Bugzilla-Status: Closed X-Bugzilla-Resolution: FIXED X-Bugzilla-Priority: --- X-Bugzilla-Assigned-To: ken@FreeBSD.org X-Bugzilla-Flags: X-Bugzilla-Changed-Fields: attachments.created Message-ID: In-Reply-To: References: Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable X-Bugzilla-URL: https://bugs.freebsd.org/bugzilla/ Auto-Submitted: auto-generated MIME-Version: 1.0 X-BeenThere: freebsd-scsi@freebsd.org X-Mailman-Version: 2.1.29 Precedence: list List-Id: SCSI subsystem List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 28 Nov 2019 14:37:37 -0000 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D219857 --- Comment #29 from Leandro Lupori --- Created attachment 209512 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D209512&action= =3Dedit Fix system hang on boot This patch fixes the system hanging on boot.
