Hi Alan,

thanks for your answer.

Here cleaned output of journalctl, removed mainly networkmanager stuff.

This is about a wake up after sleep, where before the stick was ok.

More details necessary, let me know.

Thanks

Norbert

I would have preferred to see the output from dmesg, as I requested.
But never mind, there probably isn't enough information in either log.

Please collect a usbmon trace for that bus (bus 3), starting before the 
suspend and ending after the resume.

Hi Alan,

sorry for the journalctl output. I have now done the following:L

* boot into 3.17-rc7
* mount the usb stick (recovery completed)
* unmount, mount, unmount - just to be sure all is fine
* started usbmon capturing on bus 3
* mount the usb stick
* suspend to ram
* wake up
	now the stick is "officially" mounted (/proc/mounts)
* umount 
	error messages pop up
* try to mount
	more error messages
* capture dmesg output
* stip usbmon

The two files are available here:
	http://www.preining.info/kernel/3.mon.out.gz (size 21596)
	http://www.preining.info/kernel/3.mon.out (size 216343)
and
	http://www.preining.info/kernel/dmesg.log.gz (size 17883)
	http://www.preining.info/kernel/dmesg.log (size 67734)

Just a few more things:
* usb persistency is turned on
* I checked the stick with badblocks during creation of the fs

All the best

Norbert
