Hi,
I still get LOR with my sound card and some hicup under disk load, with
today's 5.2-CURRENT. It's a UP system with following sound card.
pcm0: <Yamaha DS-1E (YMF744)> port 0xfcac-0xfcaf,0xfc00-0xfc3f mem 0xfecf0000-0xfecf7fff irq 9 at device 9.0 on pci0
pcm0: <Asahi Kasei AK4543 AC97 Codec>
Also, here's hand written LOR message:
lock order reversal
1st 0xc3405440 pcm0 (sound softc) @ dev/sound/pci/ds1.c:734
2nd 0xc3405080 pcm0:play:0 (pcm play channel) @ dev/sound/pcm/channel.c:480
