Comment 1 for bug 262944

Thank you for your bug report and for your contribution to ubuntu.

For sure, this looks like a bad bug! But if you want to take some time for it, there are some informations that might really help developers to find the cause of this problem, and maybe give you a temporary workaround.

Firstly, when you say that it fails and drop to initramfs, do you get a busybox prompt? If yes, you can often plug another device, such as a USB key to save detailed reports about the problem. If you want to give a try, you can follow these instructions :

1. Start your computer with a USB key, in the file system that you want (prefer other file system than NTFS).
2. When you get to busybox, type "fdisk -l" to see what is the device name of your USB key (probably /dev/sdb).
3. Type "mkdir /mnt/USB"
4. Mount your USB key, Ex. If your USB key is /dev/sdb and uses FAT, you can mount it by typing "mount -t vfat /dev/sdb1 /mnt/USB"
5. Once your USB key is mounted, type these commands to save reports on it :
6. lspci -nnvv > /mnt/USB/lspci-nnvv.log
7. dmesg > /mnt/USB/dmesg.log
8. uname -a > /mnt/USB/uname.log
9. cat /proc/version_signature > /mnt/USB/version.log
10. Then unmount your USB key with "umount /dev/sdb1" and come quick here to attach these precious log in the bug report :-)
