Jack,
The following in your log:
> BUG: unable to handle kernel NULL pointer dereference at 00000050
> IP: [<f8c72778>] setResumeCallBack+0x8/0x20 [agrmodem]
> *pdpt = 00000000368d4001 *pde = 0000000000000000
suggests that the problem surfaced in the setResumeCallBack() function.
The only thing that gets 'dereferenced' there is the
AgrHDACodec variable:
<<<
int fnatr setSuspendCallBack(int *SuspendCallBack)
{
SuspendPt = (int *)AgrHDACodec->patch_ops.suspend;
AgrHDACodec->patch_ops.suspend=(void *)SuspendCallBack;
return(1);
}
>>>
NULL-pointer dereference causes the module crash. So, the AgrHDACodec
must have been equal to NULL at the time of the setSuspendCallBack()
call. The only place in the code where AgrHDACodec can be set to
something other than the default value of NULL is in the HDA.c
findHDACodec() function. That function looks at the sound card and
tries to find an Agere modem codec on it. My understanding is that
047e:2892 is not an "HDA based" modem, so findHDACodec() doesn't find
any codec with vendor_id starting with 0x11c1, and AgrHDACodec remains
NULL.
Your modem needs a driver that doesn't have any HDA stuff.
Did you try the agrsm048pci-2.1.60_20100108.tar.gz or the
agrsm06pci-2.1.80~20100106.tar.gz drivers. What does you ModemData.txt
suggests?
