The really worrying thing looking at the logs locally is the serial ports are showing irq issues and becoming disabled as nobody would handle them. Errors like: [ 9.194886] irq 36: nobody cared (try booting with the "irqpoll" option) [ 9.198712] CPU: 0 PID: 127 Comm: bootlogd Not tainted [ 9.202283] Call Trace: [ 9.205611] [d1005f00] [c00a0da8] __report_bad_irq+0x50/0x138 (unreliable) [ 9.209347] [d1005f30] [c00a0cc0] note_interrupt+0x324/0x378 [ 9.212855] [d1005f70] [c009d138] handle_irq_event+0xe8/0x104 [ 9.216353] [d1005fa0] [c00a1d9c] handle_fasteoi_irq+0xc0/0x29c [ 9.219960] [d1005fc0] [c009b798] generic_handle_irq+0x40/0x5c [ 9.223496] [d1005fd0] [c00075d0] __do_irq+0x58/0x188 [ 9.226948] [d1005ff0] [c0010040] call_do_irq+0x20/0x38 [ 9.230391] [d29eda60] [c0007788] do_IRQ+0x88/0xfc [ 9.233860] [d29eda90] [c0016454] ret_from_except+0x0/0x14 [ 9.237288] --- interrupt: 501 at __setup_irq+0x3c4/0x838 [ 9.237288] LR = __setup_irq+0x790/0x838 [ 9.244155] [d29edb88] [c009f0a4] request_threaded_irq+0x114/0x1c8 [ 9.247672] [d29edbb8] [c07a5a18] pmz_startup+0x17c/0x32c [ 9.251203] [d29edbd8] [c07a1140] uart_port_startup+0x184/0x2f8 [ 9.254651] [d29edc08] [c07a1974] uart_port_activate+0x78/0xf4 [ 9.258141] [d29edc28] [c07839f8] tty_port_open+0xd4/0x170 [ 9.261579] [d29edc58] [c079db74] uart_open+0x2c/0x48 [ 9.265116] [d29edc68] [c077a288] tty_open+0x168/0x640 [ 9.268574] [d29edcd8] [c0280be8] chrdev_open+0x138/0x2a4 [ 9.272123] [d29edd18] [c027421c] do_dentry_open+0x228/0x410 [ 9.275643] [d29edd48] [c028e9f4] path_openat+0xb04/0xf28 [ 9.279184] [d29eddd8] [c02917e4] do_filp_open+0x120/0x164 [ 9.282535] [d29ede98] [c0276238] do_sys_openat2+0xd8/0x19c [ 9.285790] [d29edee8] [c0276574] sys_openat+0x88/0xdc [ 9.289096] [d29edf38] [c00160d8] ret_from_syscall+0x0/0x34 [ 9.292620] --- interrupt: c01 at 0xfec3738 [ 9.292620] LR = 0xfec36e0 [ 9.299035] handlers: [ 9.302312] [<7f7f7da8>] pmz_interrupt [ 9.305541] Disabling IRQ #36 (and the irqpoll option does not help) This is problematic as the shutdown test uses the serial interface to shut down the system. If the serial interface fails to login or run the command, game over for the test. CONFIG_SERIAL_PMACZILOG_CONSOLE complicates that handling, but doesn't provide any output or capabilities that we need. So we disable it here, and reduce the chances of issues during shutdown.
