2.6.16git14 - resume from suspend to ram faild on SATA hard drive

[Arkadiusz Miskiewicz <arekm@maven.pl>]

I'm trying to do suspend to ram on 2.6.16git14 kernel on ThinkPad Z60m with 
SATA hard drive.

Suspend/resume almost works. Unfortunately there is a problem with resume of 
hard drive.

After resume hard drive is borking and I only get bunch of SCSI errors:

The interesting thing is that kernel 2.6.14.7 resumes fine (just it takes 
several seconds for hard drive to respond after resume).

Should it resume properly with this hardware? AFAIK all needed patches are 
already merged in 2.6.16git14...
