Description of problem:
during installation, right after partitioning and while formatting 
filesystems, the installer exits with signal 11 and asks user to reboot

How reproducible:
Always

Steps to Reproduce:
1. start installation from within DOS by running 'autoboot.bat'
2. let the installer auto-partition or do it manually
3. wait for signal 11 during the formatting stage

Actual Results:
1) partitions auto-created by anaconda:
=======================================
- cannot write inode tables (stuck at 4/36)

4) manual partitioning and filesystem creation (console):

Additional info:

- installation is performed by copying: autoboot.bat, vmlinuz, initrd.img, 
loadlin.exe onto a newly formatted FAT32 partition and running the batch 
file to launch the installer (no DOS drivers/components loaded)
- installation is to be done over FTP with no CD and no floppy drives
- the system has no hardware incompatibility issues (IBM notebook, i1200 
series), which worked fine using exactly the same method with RedHat Linux 
7.1
- the installer is able to proceed only if there is no need to format 
partitions (used Debian GNU/Linux 3.0 to prepare ext3)
