Hi there,
Running ubuntu 8.04 on ibook.
Linux newton 2.6.24-17-powerpc #1 Thu May 1 13:56:51 UTC 2008 ppc GNU/Linux
a fresh hg pull of btrfs0.15, with btrfs on a lvm.
btrfsck is clean.
creation of files and dirs work, but a simple echo "a" > a, or a
cp, tar ..etc..
result in segfault/core dump of application and this is what I get from dmesg:
