Subject: xHCI Express Card failure -- ACPI related?
Date: Tue, 22 Feb 2011 16:55:13 -0800 [thread overview]
Message-ID: <20110223005513.GA2503@xanatos> (raw)
I'm having an issue with an xHCI (USB 3.0 host controller) Express Card.
This card works fine on 2.6.37, but on 2.6.38-rc5, when I plug in the
card, I get this output in dmesg:
Feb 22 16:32:28 xanatos kernel: [ 119.345996] irq 23: nobody cared (try booting with the "irqpoll" option)

I haven't had a chance to bisect yet.
Given that there wasn't any big new features added to the xHCI driver in
2.6.38, I don't think my code is the culprit here. Could it be a USB
core or ACPI issue?
