https://bugzilla.novell.com/show_bug.cgi?id=422928 Summary: USB on HP xw6600 causes irq nobody cared disabling irqs used for USB Product: openSUSE 11.0 Version: Final Platform: x86-64 OS/Version: openSUSE 11.0 Status: NEW Severity: Critical Priority: P5 - None Component: Kernel AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: ccox@endlessnow.com QAContact: qa@suse.de Found By: --- Created an attachment (id=237369) --> (https://bugzilla.novell.com/attachment.cgi?id=237369) logs for three scenarios.. usb off, usb on and usb on with kotd On the HP xw6600 workstation with the Device Security set to leave the USB ports unhidden (that is... usable), the boot.msg shows the irq's getting disabled. Attempting to reload the usb modules and scan a device yields messages about disconnects and possible the fact that the usb infrastructure is listening on the wrong irq. I believe (though I don't have the output... but can get it) openSUSE 10.3 has the same problem. So this appears to be a hardware situation not handled well by the kernel. I have many log files for examination. I have captured the dmesg, boot.msg, interrupts, hwinfo, lsmod, procinfo for the following scenarios: For openSUSE 11.0 with latest updates: USB hidden by the BIOS (basically clean logs since USB is effectively off) USB unhidden by BIOS (USB enabled) and lastly, using the kotd 2.6.27rc5 Occasionally, I can somehow get devices to attach to the machine via USB 1.1 (but not 2.0)... but I'm not sure when/why that works sometimes. Most of the time I get read errors... even if ehci_hcd is unloaded. The machine is booting with irqs managed by acpi with apic. Turning off acpi results it a non bootable machine. However the machine can boot with noapic pci=routeirq (to get the "old" way). But this doesn't solve the problem... but I can get those logs if you just have to see them. -- 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.
