The stack usage of the aic7xxx driver by itself is not all that large. 
However, there are other large stack consumers in the linux kernel.  Last I
recall, the de4x5 driver, the umsdos filesystem driver, and maybe a few
others were large consumers of the stack.  It could very well be that some
combination of these is overflowing your stack page.  What filesystems do
you use and what network drivers?
