Sorry, this should never happens. Reading zero in an irq status register
when only one IRQ is not masked and irq orccured.

This all smells like a wrong board configuration with spi/muxing/etc.

Also you told that it's half-working somehow afterwards, but this issue
should not happen and everything which based on such not working
low-level stuff will occur issues in upper-layers.
