If you cat /proc/ioports does cpqarray show any registered ioports? I
think it has a bug that means it doesn't request_region() for the
ioports it uses and this means that any other driver that tries to
auto-detect hardware by probing ports can stomp on its toes. This is
certainly the case for EISA cpqarray controllers which is where I
found this. I sent a report into or whatever the
address listed in the maintainers file is but haven't heard anything.
This bug _may_ only exist for EISA controllers - I couldn't test the
PCI version since the only machine I have with one in is running that
other o/s.
