XHCI NEC Controller not always detected

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

i wish to report a strange issue that my machine experiences with the NEC USB 3.0 PCI-Express (small slot) controller and the xhci kernel driver.
Now the machine is running

Linux xxxx 2.6.35.4 #2 SMP Wed Sep 1 10:15:04 UTC 2010 x86_64 GNU/Linux

Note that this issue was present in 2.6.34 and 2.6.33 but i though that it might get fixed.



The issue
----------------
The controller is sometimes dected and some not. I mean at some boots it is present as a PCI device (listed in pci -v as
05:00.0 USB Controller: NEC Corporation Device 0194 (rev 03) (prog-if 30)
    Flags: bus master, fast devsel, latency 0, IRQ 16
    Memory at febfe000 (64-bit, non-prefetchable) [size=8K]
    Capabilities: [50] Power Management version 3
    Capabilities: [70] MSI: Enable- Count=1/8 Maskable- 64bit+
    Capabilities: [90] MSI-X: Enable- Count=8 Masked-
    Capabilities: [a0] Express Endpoint, MSI 00
    Capabilities: [100] Advanced Error Reporting
    Capabilities: [140] Device Serial Number ff-ff-ff-ff-ff-ff-ff-ff
    Capabilities: [150] #18
    Kernel driver in use: xhci_hcd
)

and some other times it just does not exist.
Maybe it is PCI express related or xhci. I include 2 full dmesg logs ziped due to the size as well a unified diff of them.

Please cc the replies if any to the sender email (noxelia ...)
