I have a ton of drives plugged into some promise IDE cards and my motherboard's builtin ICH5 that I use for testing things.
I have not been seeing IRQ problems. However, when I have both the promise and the intel IDE drivers built into the kernel, there _is_ some sortof a race condition present, such that stat("/", &statbuf) returns the wrong value for statbuf.st_rdev about 50% of the time when booting. Instead of returning the major/minor with the correct values (/dev/hda2 on the ICH5), it instead returns some value from one of the drives on the promise card such as /dev/hdh or some such. I've tried tracking that down, but havn't been able to squash it thus far. Grrrr.
