Created attachment 661202 [details] /var/log/messages A visitir of mine brught an external "Seagate FreeAgent Go" drive. Connecting the disk to the system worked fine, in the sense that I can access and open documents on the disk (using KDE Dolphin). At the end when I used the "Safely remove drive option" the entire system froze. I could not even ssh into the system from other machines...only option being to force power off and on. I am attaching the messages file starting from mounting this disk and then the subsequent poweroff reboot. This is a DELL PRECISION T5600 wtih dual 8core cpu's and 64GB memnory.
If you can recreate this on 3.7.9 or 3.8.2 without the nvidia module loaded, please reopen.
