usb device stops working when acpi=off
I am using 220.127.116.11 built from source.
My USB key stops working when booting with acpi=off, I get:
ehci_hcd: probe of 0000:00:1d.7 failed with error -95
When booting the same kernel without that option, the error is gone and I can mount my USB device..
What is the problem here?
