I've been experiencing the same thing on my Lenovo W510. It has an nVidia card as opposed to the Radeon above, but I've had the same symptoms and the same type of dmesg errors listed. My dmesg is attached below.
It got REALLY bad after the last Ubuntu kernel update (3.2.0-20.32) - like the system is almost unusable. I am updating to 3.2.0-20.33 now, will see if it is any better. ** Attachment added: "kernelcrash.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/917668/+attachment/2955538/+files/kernelcrash.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/917668 Title: system freeze ("hard LOCKUP"), warn_slowpath_common+0x7f in sock_aio_read To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/917668/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
