...right before going into sleep mode.
I have this notebook and an external USB SATA drive hooked up to it. When I put the laptop into sleep mode, then resume its work, after a while I'll get a blank screen that essentially looks a lot like tty1, all black background and gray symbols all over the screen. Essentially, the message I get is the following:

Dec 7 11:29:18 localhost kernel: [67351.182781] note: transmission-gt[2302] exited with preempt_count 2By playing around I learned that if I kill transmission and any app that actively uses the USB disk prior to the sleep mode, and then start them after resume is finished and the disk is mounted (I use GNOME 3 in fallback mode, so it automounts the disk) everything works fine.
Now, I could ignore those messages but it gets worse. Mostly laptop will hang at a random point in time after printing that wall of text on tty1. It might take hours, or even days before this happens. Sometimes I'll find transmission in a freezed state and I may survive a couple of sleep and resume cycles but I almost never will go as far as 4 days and more in a row. The laptop will hang eventually. And the only way to avoid this is to kill off apps that use external USB drive prior to going into sleep mode.
Any ideas what's going on and how to fix this?

Thanks, however, my problem isn't speed, it's stability of the system.
