Hello,

I've found something interesting and what it seems to be the cause of
my problem.

As soon as I boot my system I can see this process being in the D-state:

[root@...ost ~]# ps aux | grep " D"
root       269  0.0  0.0      0     0 ?        D    14:11   0:00 [rtsx_usb_ms_2]
root      1424  0.0  0.0  10788  2172 pts/2    S+   14:19   0:00 grep  D
[root@...ost ~]#

I'm not exactly sure why that is, but if I do a 'rmmod rtsx_usb_ms'
the problem is gone. I already tried suspending/resuming ~40 times
after I disabled the module and the suspend/resume problem is gone.

Diego
