Cool, I did apply that patch and the periodic patch as well,
after doing so the system did not report any disable irq #23
message., but after running these two for a few days without
any issues I reverted. Then looking more into my situation,
I think ehci_hcd was getting confused with one usb device being
created by udev, and then a few seconds later another device with the
same numbers
created by hal(if thats how those two work), causing ehci_hcd to freak out.
in any case; applying the patch you had mentioned, as well
as the periodic patch did make ehci_hcd accept the two(if thats what
was happening).
