Did the RAM limits change for Home edition for 16.05.2 to 4GB?

Question

Did the limits for RAM on Home edition get changed with SFOS 16.05.2 MR2? I'm only seeing 4GB after update. Still only showing 4GB after rolling back to SFOS 16.05.1 MR-1. I was seeing 6GB usable before upgrade.

Hi All, 
 Thank you for your patience. We are finally able to investigate the issue on an affected Home User and this is mentioned in NC-18497. 
 It has been fixed in v16.05.MR5 (future MR release). 
 Cheers-

MR5 resolved the issue for me. Back to 6GB.

Also can confirm i am up with 6GB of ram on MR5. Thanks for getting this fixed. It is much appreciated. 
 New kernel option appears to be memlimit=6G. I don't see that in the normal kernel docs so they must have created it. 
 It looks like extra memory is likely getting assigned into a ram buffer based on /proc/iomem output, could be wrong. 
 
 SFVH_SO01_SFOS 16.05.5 MR-5# cat /proc/iomem | grep -i RAM 00001000-0009c7ff : System RAM 00100000-1effffff : System RAM 20200000-7b217fff : System RAM 7b293000-7b3bafff : System RAM 7bb30000-7bffffff : System RAM 100000000-205a537ff : System RAM 205a53800-207ffffff : RAM buffer

Hi All, 
 We are investigating the issue, please be sure, we are gathering as much information to provide a better RCA on this matter. Can we get the output of the following two commands: 
 
 cat /proc/meminfo | grep -i memtotal 
 free 
 
 dmidecode -t memory

Alongside, the users who saw 8 GB RAM utilization for the Home editions was a defect in the initial implementation due to which the SFOS, used to scale up to full available capacity. The defect (NC- 16008) got resolved recently. 
 Thanks
