The fix is _really_ tempting, but i think it's 2.6.26.1 material at the
earliest. I just counted about 8 red flag items in that commit:
- "assembly code"
- "fresh change"
- "suspend/resume"
- "real-mode code"
- "ACPI"
- "SMM"
- "CPU erratas"
- "boot code"
I'd say it's probably 90% fine, but it's just too much risk at this
stage i think. The regression was only found 2 weeks ago, and the commit
that broke it was upstream for 2 months (and was under testing for about
4 months).
[ We have to try to shorten the test cycle for such problems. Hopefully
in v2.6.27 we'll have CONFIG_PM_TEST_SUSPEND=y :-) ]
