[Bug 1062114] Re: usb issue on Intel chipset: abrupt mouse movements, usb keyboard loosing key events
Good day,
thank you for your mail. I was finally able to reproduce the issue. I
am attaching a dmesg output of a correct boot (please note that there
still are several unwanted IRQs), and a dmesg output of a reproduced error.
Kind regards,
Martin

usb issue: abrupt mouse movements, usb keyboard loosing key events
After some boots, the USB mouse behaves strangely (abrupt mouse
movements), also, USB keyboard tends to loose some keypresses. This
behavior occurs randomly (I can't find out what's causing this) and
lasts from the point when lightdm is displayed until the computer is
rebooted. This issue never starts to manifest during computer runtime -
either it is present right from the Ubuntu start, or it does not occur.
The issue is never present in grub menu, in Windows, nor in BIOS menu.
Sometimes, the bug manifests in multiple consecutive reboots.
Running commands as described here:
http://davidjb.com/blog/2012/06/restartreset-usb-in-ubuntu-12-04-without-rebooting
fixes the issue (until the following computer boot - not necessarily the
very next boot). There is an interesting warning in my dmesg about
ignored IRQ 17 - perhaps it is somehow related?
