Hi,
i upgrade Asus ntb UL30VT with Intel SSD 520 120GB.
After try to "hibernate-ram" ntb going succesfully to hibernation, but when i try resume,
system resume ok, but disk is gone away from system.
Filesystem is not availible and write SIGBUS errors (in /var/log/messages i have lot's of messages that you cant write to system etc).
In previous same system i have OCZ Octane S2 SSD without problem, i only copy system to new disk.
I use Gentoo linux, I try severals kernel (vanila, gentoo-sources, tuxonince, reinstaling and reconfigure hibernate-scripts, try disable AHCI access. etc..)
I found that exists lots'of users that have similar (or same) problem on other operatin systems, for example:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/930561
http://www.sevenforums.com/hardware-devices/129647-hdd-disappears-resume-sleep.html
you can search more with google (intel ssd "resume from sleep" problem)
I have actual firmware.
It seems that is problem of harddrive, I think right now then returned as a claim.
Have anyone solution on similar problem?
Thanks Zdenek
