And what might that be? 'locate sysfs' gives one hit at /etc/init.d/sysfs When I say 'sysfs stop' it stops udev. When I say 'sysfs start' it says nothing. Again 'sysfs start' says sysfs already started. That doesn't have changed anything. There's a /sys/fs/ext4/* with nothing that you seem to mean. There's a /proc/sys/fs with nothing that you seem to mean. There's one mention of acm in /proc/tty/drivers and nowhere I see anything that might be of any interest somehow.
