This is probably a Dell problem, but I'm hoping someone on the list has seen similar behavior before.
Sound input and RS232 serial input do not function on a Dell Latitude D620.
Details: - Fedora Core 5 installation, running vanilla kernel.org 2.6.16.16 and 2.6.18, results are identical. Sound input times out with an I/O error, no serial input characters are ever seen. I've tried with and without acpi, apic, and irqpoll, and see no different results.

Can anyone point me in some general direction? I have no problem hacking around in kernel source, but a good start never hurts :-)
Thanks for any assistance.
