Sparc Linux 6.2 df problem

I am having a problem with my ultra 2 and rehdat 6.2. Recently, I upgraded 
util-linux to 2.11o, and e2fsprogs to 1.27 in order to use ext3 on the 
latest kernel. I currently have the 2.4.9 kernel installed, and I want to 
update to 2.4.18. However, when I boot, and login, once I do a df -h, I 
see this:

# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda1             2.0G  145M     0 100% /
/dev/sda4             7.9G  1.9G     0 100% /usr
/dev/sda5             3.9G  362M     0 100% /usr/local
/dev/sda6             965M   52M     0 100% /var
/dev/sdb1             8.3G  2.1G     0 100% /home

Sendmail won't run properly unless I set MinFreeBlocks=-1. I don't know 
how many other programs are broken by this problem. 

Has anyone else ever experienced this problem before? I'm really at a loss 
as to what I can do to fix it.

Regards,

Paul
