This box got a builtin Promise PDC20269 UDMA133 controller. Actually it's a controller with two IDE channels. So far if using the GENERIC kernel that comes with FreeBSD, I do not experience any problems. If using my own customized kernel I am getting the following error message while booting the system: ----8<--------8<--------8<-------8<-----8<----- Interrupt storm detected on "irq10: atapci1"; throtteling interrupt source: ---->8-------->8-------->8------->8----->8----- After some trail-and-error based investigations, I did figure out that if I don't plugin any device into IDE channel two, the just described error does not occur. So it has something to do with IDE channel two. As an additional note - The controller works under Linux, FreeBSD 5.3 (GENERIC) and FreeBSD 5.2.1 (custom kernel). Any hints on how to solve this issue would be greatly appreciated.help
