Yep, here's the output:

[  168.703731] PM: thaw of devices complete after 1474.836 msecs
[  168.713213] PM: Using 1 thread(s) for compression.

		^^^^^^^^^^^ This one is probably not needed - we say 100% in the line above.

[  174.614692] PM: Wrote 300112 kbytes in 5.90 seconds (50.86 MB/s)

And then the "Saved %d%%... " could probably issue on a single line using
KERN_CONT (or what was it now with the new printk changes?):

PM: Saving image: 10%... 20%... 30%... ... 100%.
PM: Wrote 300112 kbytes in 5.90 seconds (50.86 MB/s)

which, on the whole, is nice and compact and still contains the whole
info.

Thanks.
