In drivers/irqchip/irq-realtek-intc-common.h, CLEAN_INTC_STATUS excludes bit 0: #define CLEAN_INTC_STATUS GENMASK(31, 1) When bit 0 of ISOM_ISR is set (which is included in ISOM_NORMAL_MASK 0x00000037), realtek_intc_dispatch() in drivers/irqchip/irq-realtek-intc-common.c handles irq 0 and then attempts to clear the status register: while (ints) { irq =3D __ffs(ints); ... regmap_write(data->base, bank_info->isr_offset, BIT(irq) & CLEAN_IN= TC_STATUS); } Because BIT(0) & CLEAN_INTC_STATUS evaluates to 0, regmap_write() writes 0 instead of BIT(0), leaving the interrupt status bit asserted and causing an interrupt storm. Similarly, realtek_intc_suspend() and realtek_intc_resume() write CLEAN_INTC_STATUS to info->isr_offset, which also leaves bit 0 uncleared.
