Subject: Stable regression: usb-storage is stuck in 2.6.26.5

Just updated my machine from 2.6.26.1 to 2.6.26.5, and it does not
wan to boot anymore.  It says "Initializing USB Mass Storage driver.."
(when trying to load usb-storage module) and sits here forever, every
2 minutes showing warnings about stuck processes (traces below).
With 2.6.26.1 or any previous version I never experienced this
problem.  Both 32- and 64-bits kernels behave the same way.
While waiting for usb-storage to complete, no other USB devices
works (incl. mouse and keyboard).

The machine is an AMD X2-64 (BE-2400) processor with an nVidia MCP51
chipset (lspci is below).  Motherboard is Asus M2NPV-VM, latest BIOS
(1401, dated 08/07/2008)

I'm rebuilding 2.6.26.3 for now -- trying to bisect the issue...

Thanks.
