2.4.10-pre4 + CVS == oops

[Remi Turk]

Hi,
Using 2.4.10-pre4 and either the CVS-driver or the in-kernel one,
I'm getting an oops on loading the module.

Creative EMU10K1 PCI Audio Driver, version 0.15, 18:57:43 Sep  4 2001 
PCI: Found IRQ 11 for device 00:11.0 
emu10k1: EMU10K1 rev 4 model 0x20 found, IO at 0xdc00-0xdc1f, IRQ 11 
ac97_codec: AC97  codec, id: 0x5452:0x4103 (TriTech TR28023) 

The oops: (from the CVS-version)

ksymoops 2.3.5 on i686 2.4.10-pre4.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.10-pre4/ (default)
     -m /boot/System.map-2.4.10-pre4 (specified)
