Hi there, there is also a bug report #544548. A work around is to add "noacpi" into the kernel boot line in grub, either from the grub2 boot menu (enter with "e" from the boot menu) or by adding "noacpi" to the /etc/default/grub file, and then update-grub. If you alter the /boot/grub/grub.cfg file directly, it will be overwritten on the next update-grub, eg when you update the kernel.
In my case, the line in the file is :- GRUB_CMDLINE_LINUX_DEFAULT="noacpi quiet splash" (NOTE - there is also a noapic parameter, which probably isn't the one you want - I get confused each time) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/576496 Title: Lost ata interrupt, usb hid (mouse keyboard) freezes -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
