Hi Mike,
Thanks for help. The patch works for me and boot time back to normal. So it's a fix, or just WA?
Hi Leo,
excluding up to 16 MiB of memory on every system just because that
single platform is weird is not acceptable.
I think we have to figure out
a) why that memory is so special. This is weird.
b) why the platform doesn't indicate it in a special way. Why is it
ordinary system RAM but still *that* slow?
c) how we can reliably identify such memory and exclude it.
I'll have a peek at the memory layout of that machine from boot logs
next to figure out if we can answer any of these questions.
Just to verify: this does happen on multiple machines, not just a single
one? (i.e., we're not dealing with faulty RAM)
