:I have a gtkpod process running that is unkillable. Neither -QUIT or
:-KILL help. From top:

:gtkpod successfully unmounted /ipod and then hung. I cannot kill it.
:I believe vfs_bu in the STATE column of top may be a clue. Ktrace
:returns a size 0 ktrace.out file.
It is probably related to the /ipod unmounting operation. The wait state
"vfs_bu" is "vfs_busy", which occurs when the kernel needs to access
a mount point during unmounting. For some reason it is not being
woken up. It is probably a race between two processes but the only way
I can tell for sure is if you can get a kernel core out of it.
