I encounter the same problem on another s3c24xx hardware (G500). In my
case even 8 bytes was too much and seemed to overwritte something. In
case this may help, the only solution I found to this problem was to
copy the 8 bytes just before entering suspend, and replace them with the
previous content just after resume.
