serial8250: too much work for irq11

[borderfox]

I'm after installing Ubuntu 10.04 and I want to access a usb card reader - ideally through a usb hub - but whether i slot the reader in directly or through the hub, i'm getting irq related errors (see dmesg output below). I've tried to look this up and the only suggestion I could find was to change the irq settings in bios. However, my bios version doesn't facilitate this option.

Has anyone else encountered this issue?
If so, how did you overcome it??

I managed to turn ACPI off in the BIOS - but this just gives me an unbootable machine with a continuous error: serial8250: too much work for irq11

proc/irq/11 contains these empty folders;
ehci_hcd:usb1
ohci_hcd:usb2
SiS S17012

Anyone any ideas?

It seems teh serial8250 error is not affecting the installation of the cardreader as I have managed to do that now. As I've spent much time in researching this error but failed to find much direct info on it - or at least info leading to a solution - I am going to leave it be. It doesn't appear to be preventing my use of any services on the machine as it stands right now so I will leave it as is.

I do have one last issue with the cardreader install but I will post that seperately.
