Bug#648754: [regression] suspend is flakey, "shutdown -h now" does not power off
Hello Jonathan
Thanks a lot for your advices.
Before I report upstream, here are some answers to your questions.
Hmm. Someone else reported trouble on a Compal laptop a short
while ago upstream[1].
[1] http://thread.gmane.org/gmane.linux.acpi.devel/50155
I had not found this one. Thanks. I will also contact this guy directly.
I don't suspect it will change anything, but could you test with
pci=nocrs on the kernel command line?
No change, except from the comment in the log.
I'll leave interpreting ACPI tables to the experts. Next time, please
use attachments instead of copy+paste.
I'm sorry for that.
Hm, interesting. Does pcie_aspm=off on the newer kernels make a
difference? (I don't think it will, but seems worth a try.)
No.
Because I'm incredibly lazy: can you check if this is the same as the
acpidump from the system that doesn't work (3.x)?
I did some diffs. Interesting summary:
All acpidump obtained from non-working kernels are identical.
There is a difference between the acpidump when the power off is
working and when it does not work:
$ diff acpidump-not-working acpidump-working

Next step: upstream report
Thanks again for your time.
