Subject: imx7d: Timeout waiting for hardware interrupt.

Hi,
On an imx7d board running 5.10.y the following mmc2 timeout is observed:
mmc2: Timeout waiting for hardware interrupt.

mmc2: sdhci: ============================================
The mmc2 interface is connected to an SDIO Wifi chip.
This irq timeout occurs very rarely.
Any suggestions on how to debug this?
Thanks,
Fabio Estevam
