Description of problem:
Possible IRQ issues on Lenovo T400 Laptop with ICH9 (Rev 03) hardware cause USB failures
Version-Release number of selected component (if applicable):
Insert any USB device into a Lenovo T400 running RHEL 5.2
Steps to Reproduce:
Plug in any USB device (example below is from a known-good USB flash drive)
usb 2-2: new high speed USB device using ehci_hcd and address 2
ehci_hcd 0000:00:1d.7: Unlink after no-IRQ? Controller is probably using the wrong IRQ.
usb 2-2: device not accepting address 2, error -110
usb 2-2: new high speed USB device using ehci_hcd and address 3
usb 2-2: device not accepting address 3, error -110
usb 2-2: new high speed USB device using ehci_hcd and address 4
USB device attaches correctly
I tested the same machine with the F9 install media, and USB worked correctly.

This is a pretty big problem as we are being forced to switch to this model laptop in the next couple months. Can I get an update on this issue?

dmidecode data from T400 (model 6474R1U)
So I should have paid attention to Lenovos support site. The BIOS update located here:
Repairs the IRQ issue.
Per comment #4, should this be closed as NOTABUG?
Do we need a KBase?
