FindAdapter isn't called during Crashdump test

I am writing a scsi miniport driver which support bootable PCIe RAID adapter.

a. During crash dump test, I have found that FindAdaper isn’t called by crashdump driver. So no memory.dmp can be produced in c:\windows.
b. Am I right that FindAdaper will be called during crash dump ?
c. I have limit the non-cached area size to 32 KB (less than).
d. Anything else to do ?

Thanks.
