OOPS: CRITICAL BUG IN KERNEL 2.4.0 and 2.4.1

[Marcel Silva e Sousa]

Hi all, i see a critical bug in kernel version 2.4.0 and 2.4.1, look it:
i use Linux Slackware 7.1

My Hard Disk:
hda: IBM-DPTA-372730, ATA DISK drive
hda: 53464320 sectors (27374 MB) w/1961KiB Cache, CHS=3328/255/63, UDMA(33)

I have instaled in this hard disk 3 OS (OpenBSD, Linux Slack and Windows 2K 
(NTFS).

==============
OpenBSD --> 2GB
Linux -----> 7GB
Win2k ----> 18GB
==============

Windows2K is automount in fstab. When i run command "df -h" the values of 
capacity its REALLY wrong, look it:

[root@john /]:: df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/hda1             5.4G  3.7G  1.5G  71% /
/dev/hda2             143G  136G  6.8G  95% /mnt/hda2
[root@john /]:: 

When i had kernel 2.2.18 i did not have this problem....

Sorry for my really BAD English...

Att,
