Missing PCIe interface in lspci
In the process of advising a user on getting a BCM4311 wireless device to work with bcm43xx rather than ndiswrapper, the device stopped appearing in an lspci output. The 'lspci -vn' output for this device before this failure was: 03:00.0 0280: 14e4:4311 (rev 01) Subsystem: 103c:1363 Flags: fast devsel, IRQ 21 Memory at b800 (32-bit, non-prefetchable) [size=16K] Capabilities: [40] Power Management version 2 Capabilities: [58] Message Signalled Interrupts: Mask- 64bit- Queue=0/0 Enable- Capabilities: [d0] Express Legacy Endpoint IRQ 0 Fortunately, the "customer" has two identical machines. Swapping the wireless cards showed that both BCM4311s work in the other computer, but neither works in the problem machine. Kernel Version 2.6.22.4-65.fc7 is used on both. Doing a line-by-line comparison of the dmesg outputs, the only thing that stands out is that the line Allocate Port Service[:00:03.0:pcie03] is missing on the faulty computer. This is the bridge that should connect to the device in question. The BIOS has been reset and reflashed without helping the problem. Is there anything other than some failure on the motherboard that would lead to this situation? Is there anything that we can try? The BIOS in this machine doesn't have many options.
