I'm trying to get my soundblaster 16 PnP card working in kernel 2.1.75 but
am having problems when I try to load the sb.o module. I'm using isapnp
to set up the card and this is an output of what the card is being set to.

Board 1 has Identity e5 ff ff ff ff 70 00 8c 0e: CTL0070 Serial No -1 [checksum e5]
Peek(CTL0070/-1)[0][0x70](INT 0) is 0x0702, (7,2)
Peek(CTL0070/-1)[0][0x74](DMA 0) is 0x01, (1)
Peek(CTL0070/-1)[0][0x75](DMA 1) is 0x05, (5)
Peek(CTL0070/-1)[0][0x60](IO 0) is 0x0220, (2,32)
Peek(CTL0070/-1)[0][0x62](IO 1) is 0x0330, (3,48)

My kernel config is set to match.

SBC_BASE=220
SBC_IRQ=7
SBC_DMA=1
SBC_DMA2=5
SB_MPU_BASE=330

When I try to load the sb.o module, I get the following output.

/lib/modules/2.1.75/misc/sb.o: init_module: Device or resource busy
sound: Device or resource busy

According to the docs, this would mean a resource conflict, but as you can
see from the output of my /proc/interrupts, /proc/ioports, and /proc/dma,
no such conflict exists.

I'm not really sure what debugging to do next, so if anyone has any clues,
I'd be most appreciative.

Thanks,
