Maybe not related, but I suspect you have the default
"reserved blocks percentage" (5%). That would account
for the discrepancy between size / used / avail.
5% is 1.9 GB and that's a LOT of space to reserve for root.
You can set it with tune2fs, see the man page.

couldn't hurt to fsck... well, it shouldn't ;-)

I've seen similar behavior with ext3 but I *think* in that
case I had a process that wouldnt' let go of the file.
THe space won't get actually freed while that's true.
Kill should fix that but IIRC it didn't. Reboot showed the
free space I expected.
