After booting kubuntu-alpha3 from USB, and running the installer the kernel reports
kernel BUG at /build/builddd/linux-3.0.0/fs/btrfs/super.c:984
Invalid opcode: 0000 [#1] SMP
EIP is at btrfs_calc_avail_data_space + 0x375/0x380
call trace:
? kmem_cache_alloc +0x11d/0x140

I do have some btrfs partitions on the hard disk (created using Ubuntu 11.04) but none were mounted at the time the installer was run.
