So the crash is unrelated, is what you're saying? I've attached the
log if that'll
give you some more clues.
Yes, it should have nothing to do with the crash.
Attached is a crash.log-file from the serial console.

This is weird.
#define SDHCI_INT_ADMA_ERROR 0x02000000
Could you check why the the SDIO host controller is generating this kind
of interrupt?
Also, comment out the line "brcmf_msg_level = BRCMF_ERROR_VAL;" in
brcmf_c_init of dhd_common.c. Then insert fullmac module by
insmod brcmfmac.ko brcmf_msg_level=0x7. This will give you a more detail
log of brcmfmac. But I am suspecting even the first SDIO read command
failed.
