I have a MAD16-based sound card, actually a Reveal SC400, in Windows Sound
System mode. It's on 0x530, IRQ 10, and DMA 1.
The following commands went fine:
mercury:/lib/modules/2.1.90/misc# insmod sound
mercury:/lib/modules/2.1.90/misc# insmod ad1848
mercury:/lib/modules/2.1.90/misc# insmod uart401
# Hey I was just trying to make it happy :)
# Scary thing is it actually detected something SB-like at 0x220
mercury:/lib/modules/2.1.90/misc# insmod sb io=0x220 irq=0 dma=0
mercury:/lib/modules/2.1.90/misc# insmod mad16 io=0x530 irq=10 dma=1
And then sound works great.
Upon rmmoding the mad16 driver, I got a "Trying to free free IRQ10"
message. I tried to do "cat /proc/interrupts" and got an Oops each time,
which I failed to record in any way :( I let things sit for a minute or
so, then tried cat again. It returned some greek in the entry for IRQ10 so
I looked at it with less:
CPU0
0: 188971 XT PIC timer
1: 7246 XT PIC keyboard
2: 0 XT PIC cascade
3: 8567 XT PIC serial
4: 494 XT PIC serial
8: 2 XT PIC rtc
10: 0 XT PIC <83><C4>^D<C3><C3><7>khm
11: 1 XT PIC NE2000
12: 6265 XT PIC ncr53c8xx
13: 1 XT PIC fpu
15: 2 XT PIC
Then just for kicks I tried reloading the mad16 module. (the other drivers
(sound,ad1848,uart401,sb) were still loaded) That spat out several pages
of Oops's and left every key combination except shift-pgup/pgdn dead.
Anyway, I wrote down most of the last Oops:
Page fault from irq handler: 0002
CPU: 0
EIP: 0010:[<c1d1bf80>]
EFLAGS: 00010246

00000400
[At this point my hand was aching too much to write down the call trace :)]
Code: 00 00 00 00 47 cd 2a 00 00 04 00 00 05 08 05 08 8e 9a 55 00
Aiee, killing interrupt handler
I can't find anything near c07bc764 or c1d1bf80 in my System.map - it tops
out at c02125d4.
P.S: You guys rock. Dave Miller, I'd like to thank you for your very quick
response to my earlier message. 2.1.90 is looking very very nice.
Also, are there any plans for a piece of documentation that lists all
module options and what they do, kind of like the BootPrompt HOWTO? Or am
I just blind haven't seen it? If not, I'd be willing to help maintain such
a document. It'd be very very useful for at least me. (Although it looks
like it would have kept me from discovering the proceeding :)
