As a follow-up on this morning's email , I narrowed down the issue
to the PCA9538 expander driver. For some reason, when
CONFIG_GPIO_PCA953X_IRQ is enabled, interrupts will eventually go
unhandled, causing the kernel to complain loudly and disable the
respective interrupt line. I never had this problem on OpenWrt 19.07
with Linux 4.14.x.
Any suggestions (apart from disabling CONFIG_GPIO_PCA953X_IRQ or
passing irqpoll in the kernel command line)?
