Jesse, I think this should go into Linus' tree sooner rather than later.
please forward to -stable as well. this is a regression since the card
works with older kernels.
Which kernel version introduced the regression?
I'm not sure. I know that 2.6.24 Debian EThch-and-a-half worked, 2.6.27+
failed. how critical is it to narrow down exactly where the problem crept
in?
Yinghai Lu, Matthew Wilcox,
can either of you identify where the problem would have appeared?
Do we not need mpt-fix-enable-lsi-sas-to-use-msi-as-default.patch as
well, to fix this regression?
I don't know. the current -git kernel fails, but with these two patches
works. I haven't tried backporting these patches (if there are any changes
at all needed I probably won't be able to do it)
David Lang
I sent mpt-fix-enable-lsi-sas-to-use-msi-as-default.patch to the
maintainers a week ago and it was ignored, along with everything else.
If this happens again I shall merge it under my own cognisance, along
with everything else.
