This is a multi-part message in MIME format. --------------050801040103030204060509 Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 7bit Hello current, with a recent 5.2-CURRENT (at least after the statfs changes, it worked before!) the internal sound of my Gigabyte GA6VTXD (Bios: F2) does not generate interrupts any more when I use acpi! The machine is dual 1GHZ P3 with 1GB RAM and a VIA 694 Chipset. $ cat /dev/sndstat FreeBSD Audio Driver (newpcm) Installed devices: pcm0: <VIA VT82C686A> at io 0xd400 irq 10 (1p/1r/0v channels duplex default) Sound is either very sluggish or not working at all, and I am getting the following message: $ dmesg | fgrep pcm0:play pcm0:play:0: play interrupt timeout, channel dead When I look at the vmstat output $ vmstat -i | fgrep irq10 irq10: pcm0 45 0 the number of interrupts generated stays at 45 constantly, no matter what I am running that generates sound (mplayer, xmms, mp3blaster ...) When I do not use acpi everything is fine! This is happening with my custom kernel, as well as with GENERIC. I have attached the verbose dmesg out of a boot with and without acpi and the output of "acpidump -t -d -o /dev/null > GA6VTXD_F2.asl" Any suggestions? Thank you Michael --------------050801040103030204060509--
