Thanks for your help on this. I have narrowed it down to commit
"c22ce143d15eb288543fe9873e1c5ac1c01b69a1 x86: cache pollution aware
__copy_from_user_ll()". This fits with the errors I'm getting, so now I need
to find out if I can safely ignore this patch, or does it have to be modified?
This is my first Linux bug in many years of simply using it, so I'm a little
nervous!
Just to make sure, if you disable CONFIG_X86_INTEL_USERCOPY, the
corruption goes away?
It took some fiddling to disable (edit arch/i386/Kconfig.cpu) but that has fixed it. Many thanks!
Does this need to be reported as a bug? Or should the kernel config scripts be changed to enable this option to be easily turned off?
Neil.
