[Bug 422928] New: USB on HP xw6600 causes irq nobody cared disabling irqs used for USB
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.

THIS IS NOT A FIX... just an fyi. I noticed that usb5 was on a clear interrupt (nothing else and most specifically NO interrupt count)... that is to say... appears to be a good set of ports if I can find them. Turns out, these are the front ports of the unit. So... first I need to disable ehci_hcd (since that will ride all of the ports and it's the first thing to tank because of the spurious interrupts). I didn't know how to do this "correctly", so I renamed the kernel module to something unrecognizable. But I believe the USB stuff is brought in dynamically be the detection of the hubs and I think when ehci-hcd fails, the rest don't come in... (I may be wrong on this one)... so I had uhci-hcd brought into the initrd (to make sure it's there)... then I plugged my device into the front side port... and voila! This at least has curbed my anger level... this is still a problem... it's either a hw issue or an issue because the other usb ports (and all encompassing ehci) are on interrupts that are shared with other things. Somebody told me that the usb driver doesn't receive interrupts (???). I'm going based on what is seen via /proc/interrupts... there I see usb ports (hubs) on interrupts. usb5 was clear... leading me to this workaround for my one important device (usb tv tuner acting as my pvr). -- 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.

Hmmm... This is the first time I see ata_piix taking down interrupts which aren't assigned to it. I wonder what happens if uhci and ehci are loaded first and then ata_piix is loaded. I couldn't find any option to easily achieve that in the current. cc'ing Thomas for the possible IRQ routing issue. Thomas, loading uhci, ehci and ata_piix cause nobody cared on IRQ take IRQ 16 and 18 down by causing IRQ storm. The ata_piix controller is assigned IRQ 18, so I'm a bit skeptical about the role of ata_piix but we never know. Does anything ring a bell?

To keep things simple lets focus on the two used here: 1. /etc/sysconfig/kernel modules There is a variable in that file that defines which modules should be loaded (order is kept!) on bootup. This is done very early (at the end of boot-start.sh). In a normal setup yast puts storage controller devices in here. 2. udev Every mkinitrd module can define a set of modules it wants to load using udev. Here is where USB drivers come in. Udev gets loaded at a later point and has its own logic to define orders. If I understand you correctly you actually want to define a module loading order, not really go into the shell. If that's what you want, simply define an order in /etc/sysconfig/kernel that you like. The modules there will be modprobe'd in that exact order. In case you really need a shell, just add a line saying "bash" as the last line in /lib/mkinitrd/scripts/boot-start.sh and run mkinitrd. -- 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.

I did it. The "bimbo" module did sit on top of irq 16, but didn't seem to work for 18.
Yeah, it grabs the interrupt in an unshared manner. If there is already a driver sitting on there, it won't grab it.

The values are way to high if it is right after a reboot. What all other interrupts rise the same speed as this one? Are there similar values for any other interrupt number?

Do you want all of the modules when I run lspci?? Let me know what options you want when I run that. Pavel, moving to noapic nolapic just moves the interrupts down to 3 and 5... but still they get a ton of interrupts upon boot (on processor 0). Let me know if you want any of the messages from that run. Sorry about the nvidia thing.... I don't run Windows, so I need everything to work... and there isn't an alternative out there... not yet. For any extra tests from here forward, I'll make sure to NOT have the nvidia module just so it's not a convenient scapegoat or at least doesn't cause some sort of problem.

I don't know about USB, but this looks to me like a nice debug param that is worth posting upstream? Chris: AFAIK all USB drivers are loaded early in initrd already since 11.1. Therefore you may have to use /etc/modprobe.conf.local, e.g.: options usbcore ignored_pci_device=0000:00:13.2 Then rebuild the initrd: mkinitrd the modprobe.conf{,.local} configs will also be copied to the initrd and the configs will be recognized by udev/modprobe there then. Unfortunately you have to reboot for every test then. Do you get a working system by excluding a specific (uhci) usb device? If yes, which one is it? IMO we need a boot param to tell udev to not load broken modules, similar like linuxrc is doing: broken_modules=usbcore,uhci_hcd -> Adding Kai, no need to answer, just for thinking about a possible udev enhancement :) -- 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.

Turns out it was my Qlogic QLE2360 board that caused all of the problems. I replaced it with a QLE2462 and the problem went away. When I tried that old QLE2360 in other PCIe slots... the machine wouldn't even post. Bad board... not sure if I have a bad board, or if it's just a bad design in general. -- 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.
