That should definitely be fixed. Do we enable ECRC unconditionally,
or only when we boot with "pci=ecrc=on"? The doc
(Documentation/kernel-parameters.txt) suggests the latter.
It would be ideal if we could try to turn on ECRC all the time by
default for paths that support it. I suppose there's some risk that
we'd trip over broken hardware. If that's an issue, we could consider
turning it on all the time on machines newer than X (that's easy on
x86, where we have a DMI BIOS date, but maybe not so easy on other
arches).
ecrc=on kernel option works like "force on" rather than just a simple on.
I agree we should enable it by default.
