Bug#689368: Mouse and keyboard freeze on Ivy Bridge platform
Hi,
I am encountering random keyboard and mouse freezes which can only be resolved by a hard reset (by pushing the power switch of the computer case).
I have this frequent and irritating issue with two differents Ivy Bridge platforms:
1. Processor: Intel Core i5 3450 (IGP HD 2500)
Motherboard: MSI Z77A-G43 (with uptodate BIOS)
2. Processor: Intel Core i5 3570K (IGP HD 4000)
Motherboard: ASUS P8Z77-V LX (with uptodate BIOS)
I use Debian on these platforms and I tried several Linux kernels:
* linux-image-3.2.0-3-amd64 (package from Debian testing)
* linux-image-3.4-trunk-amd64 (package from Debian experimental)
* linux-image-3.5-trunk-amd64 (package from Debian experimental)
I pointed out this bug to the Debian kernel team:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=689368
The mouse and keyboard are both USB devices and it seems that the bug is coming from the echci-hcd module:

I attached the dmesg output and the kern.log file to my first message to Debian:
* http://bugs.debian.org/cgi-bin/bugreport.cgi?msg=35;filename=dmesg.20121001-231244;att=1;bug=689268
* http://bugs.debian.org/cgi-bin/bugreport.cgi?msg=35;filename=kern.log.20121001-232320.gz;att=2;bug=689268
As mentioned to the Debian maintainers, this bug is very frequent (I had up to four freezes in an hour) and my PC are really unusable!
Can I run additional tests or give you additional informations to help you resolve this painful bug?
