I just got a new machine, an HP Kayak/XA with a PIII/500, 256 MB of RAM and
2x 9 GB of disk. It has a builtin sound card on the motherboard,
apparently a soundblaster clone of some sort on the ISA bus.
FreeBSD Audio Driver (newpcm) Nov 15 1999 14:52:14
Installed devices:
pcm0: <SoundBlaster Pro 3.2> at io 0x220 irq 5 drq 0:1 (1/1 channels duplex)
^^^^
(do I have to worry here ?)
I have current sources from a few days ago and configured newpcm as
follow. The card is recognised at boot time w/o problem.
Everytime I try to use mpg123 to play some music, the machine panic with
"unaligned write 1522, 4". Note that using
device pcm0 at isa0 port 0x220 irq 5 drq 1 flags 0x10
OR
device pcm0 at isa? port ? irq 5 drq 1 flags 0x10
doesn't make any difference.
Here are the registers:
cs 0x8
ds 0xc0f10010
es 0x10
fs 0xc0e80010
ss 0x10
eax 0x12
ecx 0x780
ebx 0xc022cb8f (db_lengths+0x1d7)
edx 0xc0227278 (ac97recdevs+0x654)
esp 0xcccddd8c
ebp 0xcccddd94
esi 0x100
edi 0xc0cfea00
efl 0x246
panic: unaligned write 1522, 4
