#14 chdir call hangs under certain circumstances

[Steffen Mueller]

I use supermount for my Teac scsi cdrom and my scsi
burner and a cardreader.

The problems occur only with the cdrom and card reader,
the burner is fine.
I'm writing a file manager in c and if there is no
media inside the device and i do a chdir call _after_
i've already done an opendir call, chdir hangs and
never returns.

Changing the order, ie. doing the chdir call first and
then the opendir call fixes the problem.

I'm using the debian kernel patch with kernel 2.4.24
