I have a lot of spurious interrupts on my Pine64. Even in idle single user mode: # pstree -+= 00001 root /sbin/init -- \-+= 01783 root -sh (sh) \-+= 01804 root pstree \--- 01805 root ps -axwwo user,pid,ppid,pgid,command # gic0: Spurious interrupt detected: last irq: 27 on CPU3 gic0: Spurious interrupt detected: last irq: 27 on CPU0 gic0: Spurious interrupt detected: last irq: 27 on CPU2 gic0: Spurious interrupt detected: last irq: 114 on CPU1 gic0: Spurious interrupt detected: last irq: 27 on CPU3 gic0: Spurious interrupt detected: last irq: 27 on CPU3 gic0: Spurious interrupt detected: last irq: 114 on CPU1 gic0: Spurious interrupt detected: last irq: 27 on CPU2 gic0: Spurious interrupt detected: last irq: 27 on CPU2 gic0: Spurious interrupt detected: last irq: 27 on CPU2 gic0: gic0: Spurious interrupt detected: last irq: 27 on CPU3 Spurious interrupt detected: last irq: 27 on CPU0 gic0: Spurious interrupt detected: last irq: 27 on CPU0 gic0: Spurious interrupt detected: last irq: 27 on CPU0 gic0: Spurious interrupt detected: last irq: 27 on CPU0 gic0: Spurious interrupt detected: last irq: 114 on CPU1 gic0: Spurious interrupt detected: last irq: 27 on CPU0 gic0: Spurious interrupt detected: last irq: 27 on CPU0 When building world (3 threads) the frequency is about a few each second, idle perhaps a few each hour. I have ethernet connected and a small USB hard disk with it's own power supply, which hosts /usr/{src,obj,ports}. In addition I noticed an ethernet lock up from time to time. Executing "dmesg" in a ssh session is often sufficient to trigger it. The weird thing is that after some boots (perhaps 1 out of 10) the spurious interrupts do not happen! I have not been able to detect a pattern here. Can others reproduce these findings? Thanks in advance for any hints.
