我有一台旧的 Raspberry Pi 2B v1.1 (BCM2836)。想用它做多用途家用迷你服务器。
刷入并运行 Ubuntu Server 22.04.3 armhf 一切正常。几个小时后，内核崩溃，不得不重启 RPi 才能恢复运行。
当前运行内核 5.15.0-1041-raspi。
由于无法追踪内核恐慌日志，我将 HDMI 端口连接到外部显示器以进一步调查该问题。
Kernel panic - not syncing: Fatal exception in interrupt.
...
...
bcm2836_arm_irqchip_handle_irq ...
...
捕获内核恐慌后附加了内容，有什么办法可以解决这个问题吗？
