Description amistry 2006-05-14 21:20:27 UTC 

There are several race conditions is the ugen driver that make it easy to panic the system when a device is detached during an IO operation.  There are also panics when select() and poll() are used on ugen device endpoints.
The attached patch fixes these issues.  The patch also fixes the current PRs:
usb/94311
usb/68232

Some of these issues are relevant to NetBSD and probably OpenBSD  and DragonflyBSD.
