Description: When I put the machine into suspend, the screen
goes black and the CPU fan stops spinning. As well, my
external HDD (USB/eSATA) stops spinning and the light turns
off but only for about 1 sec. After that short time, the
drive spins up again but everything else in the machine
remains in suspended.
I verified that this is the case on two different machines, one laptop and one desktop. Additional info: * package version(s) pm-utils 1.4.1-5. * config and/or log files etc. I have not modified any of the package config files. Steps to reproduce: 1) Attach a USB external HDD. Does not matter if the partition(s) are mounted or not. 2) Suspend the machine either by using a button in the DE, or by running /usr/sbin/pm-suspend |
pm-suspend.log

Probably your system sends a suspend signal to the connected drive, causing the spindown. After that the USB controller is suspended. Probably your disk detects a change here and spins up again.
Can you verify this problem with a different external drive or with windows? Also, when you suspend, is the USB port still powered? You can verify this with a USB phone charger cable for example.
