>Description:
-current kernels have been behaving very strangely for me since around
late December 2000... ls -a of a directory on a ffs filesystem doesn't
show anything at all, but I can ls a specific file if I know the name,
and I can read the file just fine. However, if I create a file in that
directory, I'm then able to ls it. On the other hand, ls of an iso9660
CDROM seems to work just fine, as does a NFS filesystem. Programs run
just fine...

Also, dd from raw disk devices immediately returns EOF (no error
messages from the kernel) without reading anything.

See the thread titled "Problem with new esp driver? [on mac68k] (or
maybe not)" on port-mac68k around 12/2000 and 1/2001 for my original
messages on the subject.

Booted single-user mode, ifconfiged up the ethernet, then mounted a
few things:
