幾乎每天都有核心恐慌，為什麼？

執行最新版本的 CentOS 5 64。幾乎每天都在完全隨機的時間獲取這些。盒子是一個文件傳送機器，通常發送大約 2.3Gbit

/sys/devices/pci0000:00/0000:00:1e.0/0000:0b:01.0

映射到 PCI 子設備——執行以下操作：

lspci -v | grep "0b:01.0"

…辨識該項目，然後“lspci -vv”以了解有關該特定設備的更多資訊。我不是核心專家，但這看起來像是該設備的 IRQ 問題。在我的系統上，父項 (00:1e.0) 是一個 Intel PCI 橋，我的子設備是 SD 卡讀卡器、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)

希望這可以幫助。
