AI生成コンテンツ: IRQ line-sharing among multiple devices in Linux-based systems can cause unhandled interrupts, leading to kernel failures. When an IRQ remains unserviced, the Linux kernel disables the IRQ line, potentially affecting all devices sharing it. This behavior arises after a threshold of unhandled interrupts triggers a diagnostic message and disables the IRQ. Solutions include allocating dedicated IRQs, masking interrupts via OTP or bootloader, and managing driver installation order. Specific recommendations for PMIC devices like DA9210 and DA9063 address interrupt masks and fault log clearance to mitigate such issues.
