Might this be related to shutdowns taking a long time to actually
unmount fs...
I noticed since I upped the kernel to an 2.4.10 release ( dont know the
exact checkout)
shutdowns hang on umount for a significant larger period... as in taking
2-3 minutes istd of 20-30 secs.
I also noticed a relationship with the write activity on that disk.
Which did not occur with the 1.0.1 release...
