Comment 2 for bug 282220

I have exactly the same behaviour on my Thinkpad X31, fully updated 8.10. For hardy, hibernate had always worked faultlessly. The machine does occasionally resume successfully. On initial hibernate, I get a thaw error of -16, the full messages disappears before I can write it down but I'll capture it if it is important.

I have also edited the grub boot line on start-up to remove the "quiet" and "splash" words.
This is the console output I see (I may have made type errors):
...
PM: Starting manual resume from disk
Freezing user space processes ... (elapse 0.00 seconds) done.
Freezing remaining freezable tasks ... (elapse 0.00 seconds) done.
PM: Loading image data pages (110237 pages) ... done
PM: Read 476948 kbytes in 27.20 seconds (17.53 MB/s)
Suspend console(s) (use no_console_suspend to debug)

The machine then freezes, flashing the caps lock light at about 1Hz.

I tried resuming from suspend with the no_console_suspend flag attached to the boot line (is that what I was meant to try?) and each time the machine resumed successfully.
