Looking at the BIOS manual on their web site:

ftp://download@ftp.dmp.com.tw/vortex86sx/Vortex86SX_BIOS_Manual.pdf

you can try toggling a few of the options: Try switching OnBoard IDE 
Operate Mode between Legacy Mode and Native Mode. If the kernel and the 
actual device disagree here, that could cause IRQ delivery problems. You 
can also try playing with the "Plug & Play OS" setting.
