Bug#500552: Module ehci_hcd disables IRQ, drops USB connections!
I tried the irqpoll option and it helps, sort of: I will still get the error 'disabling IRQ3', but the disk remains accessible after and does not power off. This does not fix the problem though, as any program or process will still crash or report read errors when the IRQ gets disabled.
I also tried the 2.6.24 kernel like suggested but ended up with similar results. Below is my dmesg output when running fsck.ext3:

As an additional note, booting the 2.6.24 kernel I get a message about updating the driver 'sd'. Modules uhci_hcd, ehci_hcd and yenta_socket share an IRQ but then again IRQ4 goes completely unused so to my layman brain this does not seem like an IRQ conflict. Bad hardware perhaps, or maybe the overhead required by USB2 is too much for my system (a rather old comp). I'm in over my head, let me know if I can supply you with any additional info.
