OK, this is likely an interrupt problem then. Can you add printfs to
serverworks_pci_intr() to see if there's a loop at this level (or add
a breakpoint with ddb and see what's happening here).
You can also try the attached patch to see if it helps.

BTW, if you remove rccide from your kernel you should have a slow but
working IDE system, it may help for futur tests to have a working kernel :)
