Still having an issue like this on SN78SH7 Mobo with AMD Phemon triple core, regardless of kernel - been happening since 2009 and is still happening.
Key criteria: USB devices connected, even only a hub with no other devices chained off it BIOS - USB setting for HIGH SPEED enabled - if you set it to LOW/NORMAL (still USB2) kernel boots and recognises 3 cores, mostly but not all the time. If I set USB to HIGH SPEED in bios, only 1 core of the 3 is ever recognised - even if no USB devices plugged. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/627862 Title: USB Mouse freezes randomly but consistently To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/627862/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
