That may be Pavel's position, but USB-wise we absolutely consider it a bug if Linux misbehaves in the face of routine actions like unplugging a device during suspend (or plugging in a new one). Regardless of "noresume" etc. I'd say that's true for all hotpluggable busses, in fact, but I rarely submit patches for non-USB ones like PCMCIA or CardBus. - Dave --===============017539423788236252== Content-Type: text/plain; charset="iso-8859-1" MIME-Version: 1.0 Content-Transfer-Encoding: quoted-printable Content-Disposition: inline --===============017539423788236252==--
