The same problem persists with kernel 3.4.0-030400-generic from http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4-precise/ (which is the latest precise kernel in that PPA).

It now fails to boot. More specifically, kernel 3.2.0-77 hangs in the cciss driver during initialization. The hardware is an HP ProLiant DL385 G2. The RAID controller is HP Smart Array P400: lspci -knn -s 06:01 06:01.0 RAID bus controller [0104]: Hewlett-Packard Company Smart Array P600 [103c:3220] Subsystem: Hewlett-Packard Company 3 Gb/s SAS RAID [103c:3225] Kernel driver in use: cciss Kernel modules: cciss I can observe the boot process over serial console (attached: serial-console.log). You can see the kernel messages about cciss being detected, udev messages about modprobe timing out followed by boot process timeouts and a failure to mount the root filesystem. You can also see hung task messages from the kernel (kworker/0:2 and modprobe are both hung inside cciss), and you can see some of my futile attempts to look around in the initramfs. I can boot an older kernel (2.6.32-73-server, left over from Ubuntu 10.04 LTS) just fine. I'm afraid dmesg and other bits of information collected by apport for this bug report will be misleadingly from that older kernel.
