I have this frequent and irritating issue with two differents Ivy Bridg= e platforms:=20 1. Processor: Intel Core i5 3450 (IGP HD 2500) Motherboard: MSI Z77A-G43 (with uptodate BIOS) =20 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: =20 * 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=3D689368 The mouse and keyboard are both USB devices and it seems that the bug i= s coming from the echci-hcd module: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=3D689368#24 I attached the dmesg output and the kern.log file to my first message t= o Debian: * http://bugs.debian.org/cgi-bin/bugreport.cgi?msg=3D35;filename=3Ddmes= g.20121001-231244;att=3D1;bug=3D689268 * http://bugs.debian.org/cgi-bin/bugreport.cgi?msg=3D35;filename=3Dkern= =2Elog.20121001-232320.gz;att=3D2;bug=3D689268 As mentioned to the Debian maintainers, this bug is very frequent (I ha= d 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?
