 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...)
