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: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=689368#24 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?
