Public bug reported:
Binary package hint: linux-image-2.6.22-10-generic
The recent kernel upgrade has started to create issues for my USB on my
Lenovo T61 laptop. It has three ports. The two on the left no longer
will work for usb devices. After booting I get a kernel message to the
terminal:
kernel: [ 637.852000] Disabling IRQ #21
This is what syslog is reporting before the kernel message
