Not really sure which board you have.  I have a Soyo Dragon KT400 Ultra 
Platinum.  Not aware of any recalls surrounding this board and from what I 
have read on their site, they are not either.  However, I have always had 
problems with the Hpt372 RAID controller on the board and Mandrake.  I get a 
kernel panic everytime I try to boot when the RAID option is enabled in the 
BIOS.  I did uninstall the hpt366 drivers and install hpt372 drivers and 
rebuild the kernel and this removed that particular problem but the stock 
kernel always gives a kernel panic.

I just flashed the BIOS today to the latest version from SOYO and reenabled 
RAID just to try it out and got the kernel panic again.  If you have RAID on 
your motherboard, try to turn it off and boot with the startup disk just to 
see if it makes a difference.

Also, be sure to boot with noapic and acpi=off.

Lastly, if you have more than 1 gig of RAM and a video card with more than 32 
meg of memory, be sure to use the boot options mem=860M when booting.
