Fwd: strace output

[Waldo Bastian]

The relevant part of the strace is:

stat64("/mnt/floppy",

Which seems to hang, a problem similar to this has been discussed on kfm-devel 
recently, although I'm not sure what the outcome was. The strace is 
interesting because earlier on in the strace it reads:

stat64("/mnt/floppy", {st_mode=S_IFDIR|0777, st_size=0, ...}) = 0

Maybe we fail to detect that "/mn/floppy" is a (slow) mounted filesystem 
because it wasn't mounted at some point in time? It seems like a KDirWatch is 
active on /mnt/floppy.

The actual mount/unmount actions are handled by the io-slave so they won't 
show up in the strace of the konqueror process.

Nonetheless, the fact that it hangs on a stat system call suggests that there 
is a problem at the kernel level.

Cheers,
Waldo
