The system must be reset at this point. When executing the write operation from ttyp0 the following text will be printed continuously to the console when the issue occurs: ext2_new_block: bit already set for [number] It appears that copying to an ext3 partition causes an endless loop, effectively locking up the box. This issue has been already discussed on the freebsd-fs mailing list, unfortunately without a solution: http://kerneltrap.org/mailarchive/freebsd-fs/2008/1/19/583772 This thread suggests this is an amd64-only issue. >How-To-Repeat: Mount an ext3 filesystem.
