I'm seeing the same behavior here. |
| 17 |
libreoffice-3.6.6.2 on a mostly stable system. |
| 18 |
btrfs on lvm on dmcrypt on a hybrid disk. |
| 19 |
kernel 3.7.5 pf-sources. |
| 20 |
|
| 21 |
I don't think is has anything to do with the file system or hardware. |
| 22 |
make is eating 200M memory and uses 100% CPU, not mkdir. I guess the |
| 23 |
script is just buggy. |
