I *think* I have applied the patch correctly. Please find a copy of
"git show" in the build directory attached. This should be the right
thing, shouldn't it?

Maybe I forgot to speify a particular debug option / verbosity?

I've also confirmed that the "XXX ahci_set_ipm" is present in
libahci.ko. So either I've screwed up badly when compiling the initrd,
the code is not executed or the printout does not make it into any
logfile anymore.

Yeah, that's weird.  You're enabling IPM, right?

Erm... Honestly, I have no clue. What is IPM? How do I enable it? This is a
Kubuntu Lucid 10.04 distribution, and I have not touched too much. In
particular, the kernels have been from upstream git, just with the Ubuntu config
copied over.

Maybe it is just not enabled? I am guessing that IPM might be IDE power
management? Or intelligent, integrated? Google turns up this email thread
as one of the first hits and nothing else conclusive.

Thanks,
