Subject: 2.6.23: no more free evdev devices - evdev leak?
Date: Wed, 31 Oct 2007 16:34:44 +0000 [thread overview]
Message-ID: <1193848484.5070.41.camel@localhost> (raw)
Dear all,
whenever I do a suspend resume cycle the input device's numbers are
increased until I finally run out of evdev devices. Is this a kernel
problem or some userspace program (udev/...) creating new devices all
the time?
here is the dmesg:
