CVS commit: src/sys/dev/usb

[Manuel Bouyer <bouyer%netbsd.org@localhost>]

Module Name:    src
Committed By:   bouyer
Date:           Fri Mar  6 23:40:50 UTC 2009

Modified Files:
        src/sys/dev/usb: uhci.c

Log Message:
Make it safe to call uhci_init() from a kernel thread with interrupts
enabled:
- don't enable interrupts before calling uhci_run()
- check if the controller's interrupt is enabled in uhci_intr()
The issue is that uhci_run() may tsleep(), uhci_intr1() may be called before
uhci_run() is complete and disable it because it found it halted.

Now a uhci controller can be successfully exported to a NetBSD Xen domU :)
