Hmm, the arm32 port is suffering from processes sticking in a disk wait which
has been traced to vflushbuf waiting on a vnode with I/O pending (possibly
spuriously). A fsck -d following this seems to indicate that the indirect block
address of an inode is wrong (this can show up as a bad inode type). This had
been assumed to be a port-specific problem. Does this sound like the same
problem to anyone who is an expert on such things?
