Comment 1 Zhang Rui 2015-09-29 02:21:29 UTC

the acpidump of 4.3.0.105-rc2

do you need more debugs? than please ask again.
Comment 3 Zhang Rui 2016-05-16 07:35:47 UTC 
please check if the problem still exists after rebuilding your kernel with CONFIG_STRICT_DEVMEM cleared.
Comment 4 Chen Yu 2016-05-17 09:36:05 UTC 
Hum, I found similar problem on my laptop while writing some modules, will do some investigation.
Comment 5 Chen Yu 2016-05-17 11:24:43 UTC 
Generally this problem is causing by different attribute ioremap on the same physical address(reserved region in this case), which may cause inconsistent of RAM data, so the linux detects a conflict of this and refuses to map the request address.
To figure it out, please apply this patch and append 'debugpat' during bootup, then provide the dmesg. thanks.
