记录一些极其奇怪的问题
一台机器无法启动
使用 tty 来观察，发现 ipmi 启动到这里就结束了，而 bmc 始终无反应
pci 0000:40:03.3: PCI bridge to [bus 41-42]
pci 0000:40:03.3: bridge window [io 0x3000-0x3fff]
pci 0000:40:03.3: bridge window [mem 0xc6800000-0xc6afffff]
pci 0000:40:03.3: bridge window [mem 0x2bf40000000-0x2bf4/input/input1
ACPI: button: Power Button [PWRF]
Serial: 8250/16550 driver, 4 ports, IRQ sharing disabled
最后发现，这个机器本来是 ttyS0 ，然后启动之后，会切换到 ttyS1 上。
内核警告 ACPI: Unable to map lapic to logical cpu number
原来是默认配置的 CPU 数量太少了。
默认只有 64 ，添加配置 CONFIG_NR_CPUS=128 即可
kunpeng 机器有这个警告
kunpeng 使用自己构建的内核有这个报错

果然，这是 sata 特殊问题。
应该是，scsi_complete 中:
switch (disposition) {
case SUCCESS:
scsi_finish_command(cmd);
break;
case NEEDS_RETRY:
scsi_queue_insert(cmd, SCSI_MLQUEUE_EH_RETRY);
break;
case ADD_TO_MLQUEUE:
scsi_queue_insert(cmd, SCSI_MLQUEUE_DEVICE_BUSY);
break;
default:
scsi_eh_scmd_add(cmd);
break;
}
