Just in time perhaps, suspend/resume not working on SMP machines being an increasingly significant lack, patches arrived on acpi@ the other day entitled 'SMP suspend/resume.' :) It's likely to take a fair while to test and generalise it, but to quote the author, takawata@init-main.com: : Hi, I managed to make suspend and resume work on SMP system. : The patch following is a bit crude patch, but it begin : to work on my ThinkPad X61 (core2duo system). : : TODO: (plenty, but it's great to see a good start) > Sadly, the same is also true for older chipsets (Centrino), though > there are some IBMs where it actually works. I'm not sure how suspend/resume is going on the AMD64 platforms, but most of the single CPU i386 Thinkpads seem to STR with some tweaking, and tend to be supported by acpi_ibm for function keys, fan control etc. And we hear that someone is working on suspend to disk (ACPI S4) as a Google Summer of Code project.
