When I waked up my system after s2ram I read in /var/log/messages :

but the file does exist :

-rw-r--r-- 1 tfoerste users 33768 Apr  2  2009 /lib/firmware/dvb-usb-dib0700-1.20.fw

Is this an issue with the kernel, with the kernel firmware driver or with glibc ?
Comment 1 Ulrich Drepper 2010-11-25 22:04:50 UTC 
This has nothing to do with libc.
