Greetings, FreeBSDers:
I am having problems with both sound and, most importantly, my modem.
I am using a new install of FreeBSD 3.1. (These things worked in 2.2.6.)
MODEM:
At bootup I saw this message referring to sio2, where I have my modem:
configured irq 5 not in bitmap of probed irqs 0
So I changed the IRQ in the kernel to 3, and at bootup I have this message:
configured irq 3 not in bitmap of probed irqs 0
This looks like an IRQ problem, doesn't it? I have not been able to get PPP
to work from many configurations of PPP as well as via KDE's PPP feature,
ppxp, and tkppxp. I can dial up and connect briefly, but nothing passes
through between my ISP and FreeBSD.
SOUND:
My sound card is configured thusly in the kernel and shows thusly at bootup
(and worked this way in 2.2.6):
sb0 irq 7 drq1
sbxvi0 drq 5
I can get sound to work with
cat some_sound_file.au > /dev/audio
but afterward a high-pitched whine won't go away until killed with the PID
or at reboot. CD-playing applications just crash and burn when I try to run
them.
Both these problems look like IRQ problems. But in dmesg and in my kernel
configuration file there are no conflicts that I can see. I made a list of
the IRQ #s I found in those two places:
atkbd irq 1
sio0 irq 4
sio2 irq 5, then irq 3
(sio1 and sio3 are both commented out in the kernel and don't appear at
bootup)
fdc0 irq 6 drq 2
sb0 irq 7 drq 1
sbxvi0 drq5
vga0 irq 10
PCI slot 2 irq 10
npx0 irq 13
wdc0 irq 14
wdc1 irq 15
Could the problem be the vga0 and PCI slot 2 sharing the irq # 10?
Is there a table of IRQ numbers?
Thanks in advance,
Chris Booth
