/sys/devices/pci0000:00/0000:00:1e.0/0000:0b:01.0
映射到 PCI 子设备 - 执行以下操作:
lspci -v | grep "0b:01.0"
...识别该项目,然后“lspci -vv”查找有关该特定设备的更多信息。我不是内核专家,但看起来该设备存在 IRQ 问题。在我的系统上,父项 (00:1e.0) 是 Intel PCI 桥,我拥有的子设备包括 SD 卡读卡器、我的 miniPCI wifi 卡等。
/sys/devices/pci0000:00/0000:00:1e.0/0000:03:03.0/
...
$ lspci -v | grep "00:1e.0"
00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev d3) (prog-if 01 [Subtractive decode])
....
$ lspci -v | grep "03:03.0"
03:03.0 Network controller: Intel Corporation PRO/Wireless 2200BG [Calexico2] Network Connection (rev 05)
希望这可以帮助。

可能是以下原因之一:硬件驱动程序有错误或硬件有问题。我会检查内存、CPU 和系统板。如果这种情况突然发生,很可能是其中之一。
