There is only one change in this driver code itself since 6.5 (commit b6ba0aa46138), and judging from the stack trace, it's unrelated with your problem. It's more likely a regression in the lower level code, e.g. PCI layer or arch/arm64 stuff. Could you try git bisect? thanks, Takashi From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: X-Spam-Checker-Version: SpamAssassin 3.4.0 (2014-02-07) on aws-us-west-2-korg-lkml-1.web.codeaurora.org Received: from bombadil.infradead.org (bombadil.infradead.org [198.137.202.133]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (No client certificate requested) by smtp.lore.kernel.org (Postfix) with ESMTPS id 423AEEB8FAD for ; Wed, 6 Sep 2023 06:10:43 +0000 (UTC) DKIM-Signature: v=1; a=rsa-sha256; q=dns/txt; c=relaxed/relaxed; d=lists.infradead.org; s=bombadil.20210309; h=Sender: Content-Transfer-Encoding:Content-Type:List-Subscribe:List-Help:List-Post: List-Archive:List-Unsubscribe:List-Id:MIME-Version:References:In-Reply-To: Subject:Cc:To:From:Message-ID:Date:Reply-To:Content-ID:Content-Description: Resent-Date:Resent-From:Resent-Sender:Resent-To:Resent-Cc:Resent-Message-ID: List-Owner; bh=EAydfvhwUQ+kPwWA1Q30srNTYDBOe/AfGJ3yxD5buzo=; b=4Zha8Xj+xj9OaS K5z8+PXVxKtOIRB5/tHpAaN86XFWnt4P3kQ6aZE1rOCxOkPpBG4wlN+VIlqqPPeoMi7I8eZ7GR/Iy 4akvFg22Fs3K6xPc0iwM504lh5234yIDBrDj9F/Pu2MCrkn5Q16JrbJyOpiyISfvb7UmyBZ0R9pTa UZx2dWo41p1LaPbmvZ7Qx8x4JDEFyTd4jovjHny9fUg0aBEpOyzisUqJTkDfkx+AkS+A7uKWJkZ/z fO+K+smeZMY2a1AfWqcKu69gOiKZNOFSUWX04mStA7pqKNvu8SpA0+Dcw682cZfUWjRaXJ6uxuEcu eFholScMyb8wADVwbJgA==; Received: from localhost ([::1] helo=bombadil.infradead.org) by bombadil.infradead.org with esmtp (Exim 4.96 #2 (Red Hat Linux)) id 1qdlk3-007LCa-28; Wed, 06 Sep 2023 06:10:19 +0000 Received: from smtp-out1.suse.de ([195.135.220.28]) by bombadil.infradead.org with esmtps (Exim 4.96 #2 (Red Hat Linux)) id 1qdljz-007LBX-36 for linux-arm-kernel@lists.infradead.org; Wed, 06 Sep 2023 06:10:17 +0000 Received: from imap2.suse-dmz.suse.de (imap2.suse-dmz.suse.de [192.168.254.74]) (using TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits) key-exchange X25519 server-signature ECDSA (P-521) server-digest SHA512) (No client certificate requested) by smtp-out1.suse.de (Postfix) with ESMTPS id 1BCF722437; Wed, 6 Sep 2023 06:10:10 +0000 (UTC) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=suse.de; s=susede2_rsa; t=1693980610; h=from:from:reply-to:date:date:message-id:message-id:to:to:cc:cc: mime-version:mime-version:content-type:content-type: in-reply-to:in-reply-to:references:references; bh=xdRDi5mtaCUJf5leM0kpyY2RGuxnrhxdzXOeSIODiTM=; b=wEKuigTgWaKVIOo1tcgXvoQpUNRlStYyixf5JWz39/bUoqNuP+DisKQBLILRkM2OtauJdn 2RVsD4jhgtdd04ZUesvsLN6XYWVvxHOmoQCYCywDgEPDtFOGrerNAi1d74/nF+VQkmJu/H EWUsAicW0MbJLOziBIeY10AL7EsamYM= DKIM-Signature: v=1; a=ed25519-sha256; c=relaxed/relaxed; d=suse.de; s=susede2_ed25519; t=1693980610; h=from:from:reply-to:date:date:message-id:message-id:to:to:cc:cc: mime-version:mime-version:content-type:content-type: in-reply-to:in-reply-to:references:references; bh=xdRDi5mtaCUJf5leM0kpyY2RGuxnrhxdzXOeSIODiTM=; b=Pdtq5CJUqDaHxtEVL8nw15Vp5zejZQtR/lxAsA0M0RTBFd22T3E8kBkx+HIiBwWksksp1r BaSaWkkQC+avYUCg== Received: from imap2.suse-dmz.suse.de (imap2.suse-dmz.suse.de [192.168.254.74]) (using TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits) key-exchange X25519 server-signature ECDSA (P-521) server-digest SHA512) (No client certificate requested) by imap2.suse-dmz.suse.de (Postfix) with ESMTPS id DBE8E1333E; Wed, 6 Sep 2023 06:10:09 +0000 (UTC) Received: from dovecot-director2.suse.de ([192.168.254.65]) by imap2.suse-dmz.suse.de with ESMTPSA id H7DBNMEX+GRSHAAAMHmgww (envelope-from ); Wed, 06 Sep 2023 06:10:09 +0000 Date: Wed, 06 Sep 2023 08:10:09 +0200 Message-ID: <877cp3esse.wl-tiwai@suse.de> From: Takashi Iwai To: Antonio Terceiro Cc: Jaroslav Kysela , Takashi Iwai , Catalin Marinas , Will Deacon , alsa-devel@alsa-project.org, linux-kernel@vger.kernel.org, linux-arm-kernel@lists.infradead.org Subject: Re: snd-cmipci oops during probe on arm64 (current mainline, pre-6.6-rc1) In-Reply-To: References: User-Agent: Wanderlust/2.15.9 (Almost Unreal) Emacs/27.2 Mule/6.0 MIME-Version: 1.0 (generated by SEMI-EPG 1.14.7 - "Harue") X-CRM114-Version: 20100106-BlameMichelson ( TRE 0.8.0 (BSD) ) MR-646709E3 X-CRM114-CacheID: sfid-20230905_231016_147334_DFD7896D X-CRM114-Status: GOOD ( 24.91 ) X-BeenThere: linux-arm-kernel@lists.infradead.org X-Mailman-Version: 2.1.34 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: "linux-arm-kernel" Errors-To: linux-arm-kernel-bounces+linux-arm-kernel=archiver.kernel.org@lists.infradead.org On Wed, 06 Sep 2023 00:01:01 +0200, Antonio Terceiro wrote: > > Hi, > > I'm using an arm64 workstation, and wanted to add a sound card to it.

There is only one change in this driver code itself since 6.5 (commit b6ba0aa46138), and judging from the stack trace, it's unrelated with your problem. It's more likely a regression in the lower level code, e.g. PCI layer or arch/arm64 stuff. Could you try git bisect? thanks, Takashi _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
