I'm experiencing exactly the same problem on a Sony Vaio VGN-SR21M with an ATI RADEON graphic card
01:00.0 VGA compatible controller: ATI Technologies Inc Mobility Radeon HD 3400 Series my kernel is Linux earth 2.6.35-22-generic #33-Ubuntu SMP Sun Sep 19 20:32:27 UTC 2010 x86_64 GNU/Linux and i'm on maverick updated just now installed 1 hour ago from the maverik beta. System load is almost 5.10 with nothing running and in top appear the kslowd000 process. The same problem appears in tty1 so it's NOT related to graphic card. ** Changed in: linux (Ubuntu) Status: Fix Released => Confirmed -- Mouse often hangs after upgrade to 35-2, 35-4 kernels https://bugs.launchpad.net/bugs/595764 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
