That's not surprising. In general you need to do readdir/getdents on
directories, not ordinary read().

Anyway, this appears to be the relevant part of the trace:

  1046      1 ls       CALL  __stat30(0x80510cc,0xbfbfe844)
  1046      1 ls       NAMI  "/placka/"
  1046      1 ls       RET   __stat30 0
  1046      1 ls       CALL  open(0xbbbce674,0,0)
  1046      1 ls       NAMI  "."
  1046      1 ls       RET   open 3
  1046      1 ls       CALL  fcntl(3,2,1)
  1046      1 ls       RET   fcntl 0
  1046      1 ls       CALL  fchdir(3)
  1046      1 ls       RET   fchdir 0
  1046      1 ls       CALL  open(0x8050000,4,0)
  1046      1 ls       NAMI  "/placka/"
  1046      1 ls       RET   open -1 errno 22 Invalid argument
  1046      1 ls       CALL  open(0x8050000,4,0x16)
  1046      1 ls       NAMI  "/placka/"
  1046      1 ls       RET   open -1 errno 22 Invalid argument

It looks as if it's calling open with O_NONBLOCK and smbfs doesn't
like that.

(I have no idea why it tries a second time passing 0x16 as the mode;
that's not remotely sensible. Maybe someone else reading this will
have an idea...)
