linux-18.104.22.168-rt16 + bonnie++ = crashdown
I installed a dell workstation T7500 with linux-22.214.171.124 plush preempt rt patch 16.
This system has 24G memory and 400G LSI SAS rain hard drive.
When I run "bonnie++ -s 48000M -uroot:root -d /root/bench", the system eventually run out of memory and died. I tried the same test with vanilla kernel 126.96.36.199, it is ok.
It seems the preempt kernel with large memory has some memory issue.
If there are any comments and suggestions I really appreciate.
Thanks in advance.
