Summary: IRQ 9: Nobody cared
Product: Other
Version: 2.5
KernelVersion: 2.6.22.1
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: high
Priority: P1
Component: Other
AssignedTo: other_other at kernel-bugs.osdl.org
ReportedBy: akkzilla at shallowsky.com
Most recent kernel where this bug did not occur: 2.6.18.8
Distribution: Ubuntu feisty
Hardware Environment: Vaio SR17
Software Environment: APM kernel, not ACPI (see bug 8274)
Problem Description:
(I'm splitting this off from bug 7264 at Len Brown's suggestion.)
I'm getting a message in dmesg at boot time:
irq 9: nobody cared (try booting with the "irqpoll" option)
Aside from the message, the most visible symptom is that if I run a usb mouse
through a hub, it doesn't work right ... instead of moving smoothly, it moves
only a few pixels in erratic directions (so basically isn't usable). I think
I've noticed sound flakiness too, but the USB mouse is the most reproducible.
The hardware that's known to be on IRQ 9 is the yenta pcmcia/cardbus controller
(with a 3com 3c59x cardbus ethernet card inserted), USB (with the built-in
memory stick reader plus an external hub plugged in, and a mouse plugged into
the hub), sound (Yamaha ymfpci) and firewire (nothing plugged in).
Even with all this hardware on IRQ 9, the machine used to work fine up through
2.6.18.8, but any kernel from 2.6.19 on shows the same problem.
Steps to reproduce: boot with a USB mouse plugged in through a hub. If the
mouse works immediately after booting, suspending once and resume: failure is
100% after the first suspend. (Suspend/resume works fine in .18 and earlier.)
