--- Comment #1 from Steevan <steevanxperia@gmail.com> ---


I tried contacting SuperMicro and then Intel tech support. Both suggested t=
hat
the issue could be specific to FreeBSD OS.=20

So later I tried FreeBSD 12 Beta 3 version  on this server with Xeon Gold 5=
115
CPU.

All these problems have disappeared.  In this FreeBSD 12 Beta3 also contigf=
ree
takes much more time compared to contigmalloc.=20

However  when I compare the absolute values to FreeBSD 11.x number I can see
huge improvement in FreeBSD 12 Beta 3.

Now in FreeBSD 12 Beta3 my PCIe card driver takes just a few seconds to load
and few seconds to unload.=20
However on FreeBSD 11.x it takes 2+ minutes to load and upto 15 minutes to
unload.=20

Hence it looks like the problem is with FreeBSD 11.x.=20
Hope the attached simple program in original bug report helps you guys to
reproduce this issue.=20

Best Regards,
Steevan
