Hi Alan,
Recently, I'm debugging this issue (the same symptom described by Don) on my
server. Fortunately, the issue was fixed by applying your patch posted in this
email thread. Just checked the latest kernel (3.7.4) and the mainline
(3.8-rc4), the patch was not included in those kernels. Do you have any
schedule to submit the patch to the upstream? Thanks in advance.
The list of the allocated IRQ (uhci_hcd used the shared interrupt) on my
server:
