KUbuntu LiveCD - hanging because of btrfs

Asked by Georg Grabler

I lately installed KUbuntu with the LiveCD, using btrfs as filesystems (/ and /home).

Because the system crashed (noveau driver makes my graphics card crashing with 15.04 before the first kernel update), I ended up in a borked state where it won't boot any longer.

So I went to re-install, put in the usb flash drive (which I used to install it before), and - the livecd didn't boot any longer.

I removed the quiet and splash options to see what's going on, and it seemed to hang after probing my btrfs file systems. It never got back from there. I thought maybe it's scanning the devices, and gave it 30 Minutes, but it was still at the same state.

So I booted in a different LiveCD (archlinux) and removed the btrfs file systems. After that the LiveCD did boot properly again. For this reason (and for the reason that I couldn't boot with btrfs for yet-unkown-reasons after a kernel update, a bug for that exists already), I chose ext4 now.

So I guess either btrfs tools are borked, or the at least the probing of the btrfs file systems during bootup of the livecd.

Sorry for assigning it to the installer, but this one didn't let me choose kubuntu-live as problem source. Since it's somehow related, I hope where to point this one.
