Bug Description
Hi, I had to reboot my Ubuntu manually because it freezed, but after that, It freezed in the middle of boot and said something about it cannot mount my /home partition (/dev/sda6), which is btrfs.
It is unmountable also from live-cd.
Are all of my data destroyed?
What can I do with it?
Also, I tried to report this bug using ubuntu-bug command, it asked me about few things and I answered this:
"other problem" -> "freezes or hangs during boot or usage" and it kicked me to this "xorg" bug report, I do not think it is correct, but when I tried to use "ubuntu-bug" -> "external or internal....." it offered me to report bug in sound devices. Is it a joke?
Thanks.
P.S. I add screenshots of booting my Ubuntu and also of Kubuntu live CD.
Both reports errors mounting /dev/sda6.
