Classification: openSUSE Product: openSUSE 12.3 Version: Final Platform: x86-64 OS/Version: openSUSE 12.3 Status: NEW Severity: Major Priority: P5 - None Component: Kernel AssignedTo: kernel-maintainers@forge.provo.novell.com ReportedBy: salazarlazc@gmail.com QAContact: qa-bugs@suse.de Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/28.0.1500.71 Safari/537.36 All usb 3.0 ports are not detected by the kernel's initialization routines. I've tested usb 2.0 and 3.0 devices (external hard drives and usb pen drives) on the 3.0 ports and these devices have failed to be detected. However, these devices are detected by the usb 2.0 ports, which indicates that the usb 3.0 ports are not being initialized during boot up. I've tried using the following kernels without luck 3.7.10-37.gf3c94ad-desktop desktop-3.7.10-1.16.1.x86_64 My system has an MSI A75 MA G55 motherboard with an AMD A75 chipset for the usb 3.0 controller. Reproducible: Always Steps to Reproduce: 1.Install the latest version of 12.3 with kernel desktop-3.7.10-1.16.1.x86_64 on a system that has an MSI motherboard A75-MA-G55 that supports usb 3.0. I suspect that any other MSI motherboard will do too. 2. After the linux distribution is installed, none of the usb 3.0 ports are useable. 3. Do an lsusb in superuser mode. There should be device for the 3.0 hubs but none are shown. 4. Do an lspci in superuser mode. There should be an XHCI host controller installed. This is indeed the case in my testbed. 5. Do a dmesg | grep xhci The xhci_hcd driver should of registered the usb ports detected as usb 3.0. This does not happen. Actual Results: When I try to plug a usb device (either 2.0 or 3.0) to any of the usb 3.0 ports, the device does not get detected or connected to the computer. The output of dmesg is: [ 1.496395] xhci_hcd 0000:00:10.0: can't derive routing for PCI INT A [ 1.496399] xhci_hcd 0000:00:10.0: PCI INT A: no GSI [ 1.496421] xhci_hcd 0000:00:10.0: xHCI Host Controller [ 1.496427] xhci_hcd 0000:00:10.0: new USB bus registered, assigned bus number 6 [ 1.496640] xhci_hcd 0000:00:10.0: request interrupt 255 failed [ 1.496790] xhci_hcd 0000:00:10.0: USB bus 6 deregistered [ 1.496810] xhci_hcd 0000:00:10.0: can't derive routing for PCI INT A [ 1.496812] xhci_hcd 0000:00:10.0: init 0000:00:10.0 fail, -22 [ 1.496949] xhci_hcd: probe of 0000:00:10.0 failed with error -22 [ 1.496958] xhci_hcd 0000:00:10.1: can't derive routing for PCI INT B [ 1.496960] xhci_hcd 0000:00:10.1: PCI INT B: no GSI [ 1.496972] xhci_hcd 0000:00:10.1: xHCI Host Controller [ 1.496976] xhci_hcd 0000:00:10.1: new USB bus registered, assigned bus number 6 [ 1.497145] xhci_hcd 0000:00:10.1: request interrupt 255 failed [ 1.497216] xhci_hcd 0000:00:10.1: USB bus 6 deregistered [ 1.497227] xhci_hcd 0000:00:10.1: can't derive routing for PCI INT B [ 1.497229] xhci_hcd 0000:00:10.1: init 0000:00:10.1 fail, -22 [ 1.497299] xhci_hcd: probe of 0000:00:10.1 failed with error -22 Notice that the xhci_hcd driver fails to load because of the "request interrupt 255 failed" message.

Expected Results: The usb 3.0 devices (e.g. external hard drives) should of been detected and connected. 1) There should be no errors due to xhci_hcd in the dmesg output due to the "request interrupt 255 failed" message. 2) lsusb should of listed a usb 3.0 root hub device I was able to fix the issue by doing a google search. It seems that this problem has happened before. Specially for MSI motherboards. See: https://lkml.org/lkml/2013/2/18/115 https://lkml.org/lkml/2012/2/13/453 http://comments.gmane.org/gmane.linux.kernel.pci/20481 Since, I didn't want to re-compile the kernel with the code that the previous links listed, I went ahead and passed the "acpi=noirq" flag to the kernel booting command in grub2 during boot time. After this, the problem was resolved. I think a fix should either include kernel code to handle MSI motherboards or include kernel code that will cast irq interrupt values to integers where appropiate. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
