the computer is: - Lenovo R500 with Ati Radeon 3470 ( using the properiety driver of ati ) - connected to a wireless-n router via the internal 5100agn network controller - running latest karmic kernel ( 2.6.31-18-generic ), but upgraded several times ( i think from 6.10 ) -- Lenovo X61 hangs with flashing caps lock LED. https://bugs.launchpad.net/bugs/303276 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
