Hi,

thanks. We have been running our tests with complete pileup of 12 patches 
from Intel, and the bug didn't trigger so far (and it triggers now pretty 
reliably with the unpatched kernel in the setup Karsten has established in 
our testing environment).

So the patches really seem, as far as our current testing goes, to 
at least workaround the problem.

I will now try to isolate which of the patches really fixes the problem, 
so that we could understand better what is going on and who is causing the 
corruption.

Do you think it would be possible to adapt this particular patch so that 
it spits out watnin/stacktrace when write and/or erase cycle is attempted 
but denied?

Thanks,
