This is the change which stops snd_hda from working here: % Date: Wed, 21 Mar 2007 15:39:12 +0000 (UTC) % Message-Id: <200703211539.l2LFdCQW036704@repoman.freebsd.org> % From: John Baldwin <jhb@freebsd.org> % Subject: cvs commit: src/sys/dev/acpica acpi.c % To: src-committers@freebsd.org, cvs-src@freebsd.org, cvs-all@freebsd.org % Cc: % % jhb 2007-03-21 15:39:12 UTC % % FreeBSD src repository % % Modified files: % sys/dev/acpica acpi.c % Log: % Change acpi's handling of suballocating system resources to be a little % simpler. It now can just use rman_is_region_manager() during % acpi_release_resource() to see if the the resource is suballocated from % a system resource. Also, the driver no longer needs MD knowledge about % how to setup bus space tags and handles when doing a suballocation, but % can simply rely on bus_activate_resource() in the parent setting all that % up. % % Revision Changes Path % 1.233 +39 -55 src/sys/dev/acpica/acpi.c If I update my kernel sources to Wed Mar 21 14:39:39 2007 +0000 (including the sys/modules/padlock/Makefile commit of Sam Leffler, to fix the kernel build from Wed Mar 21 17:37:13 2007 +0000), I can see that the snd_hda driver probes my sound card correctly. Updating after the commit shown above, breaks snd_hda. Updating to CVS HEAD and reverting the commit above, seems to work almost fine, but then I get the following: ACPI Exception (utmutex-0376): AE_TIME, Thread 8 could not acquire Mutex [0] [20070320] ACPI Error (exutils-0180): Could not acquire AML Interpreter mutex [20070320] ACPI Error (utmutex-0421): Mutex [0] is not acquired, cannot release [20070320] ACPI Error (exutils-0250): Could not release AML Interpreter mutex [20070320] Any idea how to proceed in fixing acpi or snd_hda itself? - Giorgos
