Cloning again because this bug still exists in F17. From the comments it looks like the problematic devices are all Logitech webcams. +++ This bug was initially created as a clone of Bug #663583 +++ +++ This bug was initially created as a clone of Bug #583168 +++ Original bug was closed due to EOL. Bug is still present in FC14. Sometimes when system starts up the system is very slow. Taking a look at the /var/log/messages file shows a large number of entries of the form: Dec 16 10:31:57 kernel: [ 2711.698066] ALSA sound/usb/clock.c:233: 3:3:3: cannot set freq 16000 to ep 0x86 And a bit less but also frequently: Dec 16 10:38:13 pulseaudio[2043]: module-alsa-card.c: Failed to find a working profile. Dec 16 10:38:13 pulseaudio[2043]: module.c: Failed to load module "module-alsa-card" (argument: "device_id="0" name="usb-046d_08c9_56B751A2-02-U0x46d0x8c9" card_name="alsa_card.usb-046d_08c9_56B751A2-02-U0x46d0x8c9" tsched=yes ignore_dB=no card_properties="module-udev-detect.discovered=1""): initialization failed. Login in is also very slow since it is unable to play the required sounds when selecting a username to use for login; this is the first indicator of this bug when using the system.
Are you still seeing this with the 3.9.4 kernel in updates-testing?
