Hi, This issue is NOT happened on older kernel. It is just started from 3.2.0-*.I tried to install the v3.2-rc4 which is downloaded from:http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.2-rc4-oneiric/ linux-headers-3.2.0-030200rc4_3.2.0-030200rc4.201112012035_all.deblinux-headers-3.2.0-030200rc4-generic_3.2.0-030200rc4.201112012035_i386.deblinux-image-3.2.0-030200rc4-generic_3.2.0-030200rc4.201112012035_i386.deb This issue will be gone and the system will run smoothly. But the wireless card (Intel Centrino Wireless-N 1000) will beunusable with this kernel.
