Thanks for your clarify.
Enable PAE on x86 32bit kernel, 8G memory, movablecore=6.5G
Could you please provide more info ?
Such as the whole kernel commondline. And did this happen after
you applied these patches ? What is the output without these
patches ?
This result is without the patches, I didn't add more kernel
commandline, just movablecore=6.5G, but output as you see is strange, so
what happened?
Hi Simon,
For now, I'm not quite sure what happened. Could you please provide the
output without the movablecore=6.5G option ?
Seeing from your output, your totalpages=2051391, which is about 8G. But
the memory mapped for your node 0 is obviously not enough.
When we have high memory, ZONE_MOVABLE is taken from ZONE_HIGH. So the
first line, 8304MB HIGHMEM available is also strange.
So I think we need more info to find out the problem. :)
Thank. :)
Thanks. :)
