Another suspend-to-RAM problem

bl0tt0 · 04-24-2006, 03:45 PM

Sorry for bringing up a long dead post, but I'm having a similar problem to that of the original poster. I've gotten suspend to RAM working fine while running X, but when I'm in the framebuffer console, I get the exact same results that they do. I'm still looking for a reason for this, and I haven't managed to find anything. Can anyone give some insight into the problem, or whether it's something that the folks working on the kernel know about?

I had the same problem but after compiling the kernel with most USB options under 'Device Drivers -> USB Support' being compiled as modules and unloading thenm while suspending resulted in suspend working perfectly with the following script : (Note - vbetool is used to get the LCD to turn back on)

Code:

#!/bin/sh

# switch to virtual terminal 1 to avoid graphics
# corruption in X
chvt 1

#remove modules
rmmod uhci_hcd 
rmmod ehci_hcd

# write all unwritten data (just in case)
sync

# suspend display
vbetool vbestate save > /tmp/db
vbetool dpms suspend

# suspend
echo -n mem > /sys/power/state

# resume display
vbetool vbestate restore < /tmp/db
vbetool dpms on

modprobe ehci_hcd
modprobe uhci_hcd

rm /tmp/db
# switch back to virtual terminal 7 (running X)
chvt 7

I hope this works for you guys. I had to bust my ass to try and get this working and will be very glad to know that it helped others.
