每当我lspci在系统（运行 Ubuntu 16.04 的 dell xps15 cnx95604）上运行该命令时，它都不会返回任何结果，也无法终止该进程。在某些情况下，它甚至会导致系统崩溃。
journalctl -f运行前的输出lspci（显示多条此类消息）：
Feb 06 16:26:21 lenny kernel: pcieport 0000:00:1c.0: AER: Corrected error received: id=00e0

Feb 06 16:26:21 lenny kernel: pcieport 0000:00:1c.0: [12] Replay Timer Timeout
journalctl -f运行时的输出lspci：
Feb 06 16:27:51 lenny kernel: nouveau 0000:01:00.0: Refused to change power state, currently in D3
Feb 06 16:27:51 lenny kernel: nouveau 0000:01:00.0: Refused to change power state, currently in D3

Feb 06 16:27:51 lenny kernel: nouveau 0000:01:00.0: DRM: resuming object tree...
随后，系统崩溃。
关于如何解决这个问题您有什么想法吗？
编辑： 我再次尝试，这次得到以下输出：
