Hi,
I met this too when I executed below command to trigger a kcore reading.
I wanted to do a simple testing during system running and got this.
makedumpfile --mem-usage /proc/kcore
Later I tried your above objdump testing, it corrupted system too.
What do you mean with "corrupted system too" -- did it not only fail to
dump the system, but also actually harmed the system?
@Lorenzo do you plan on reproduce + fix, or should we consider reverting
that change?

Apologies I mised this, I have been very busy lately not least with book :)
Concerning, I will take a look as I get a chance. I think the whole series
would have to be reverted which would be... depressing... as other patches
in series eliminates the bounce buffer altogether.
I spotted

today, maybe that's related.
