Hi!
Seeing a couple of MSI changes in there, on a hunch I booted latest tree with
pci=nomsi, and it resumed again.
Any ideas how to further debug this?
I'll try backing out individual changes from that merge tomorrow.
Thanks.
Of those msi patches you have identified I don't see anything really
obvious. And you actually marked them as good in your bisect so
I don't expect it is core problem.
We do have a known e1000 regression, with msi and suspend/resume.
still? I tested this against rc3 and it's mostly just fine. even with msi
enabled.
So it is possible the nomsi avoided a driver problem. Especially
as we have a number of driver changes on the on Linus's side of
that merge.
I also know we have some known issues with pci_save_state and
pci_restore_state that require them to be paired for correct
operation. For suspend and resume that is not generally a problem.
I have fixes for the pci_save_state and pci_restore_state in the -mm
and gregkh tree's. Since they also happen to fix the e1000 driver as
a side effect they are worth looking at, at least if you have an
e1000.
hey, please include me on those!
I don't have a clue which hardware the x60 has so I don't know which
drivers it would be using.
x60 indeed has e1000.
yup.
